Which of the following statements is/are INCORRECT? A. The ratio of the force of gravitation between two masses, m1 and m2, kept at a distance R on the earth and on the moon is 1:1. B. Nm2/kg2 is the SI unit of G. C. The value of G depends on the distance between the bodies. D. The value of G depends on the masses of the bodies.

Which of the following statements is/are INCORRECT? A. The ratio of the force of gravitation between two masses, m1 and m2, kept at a distance R on the earth and on the moon is 1:1. B. Nm2/kg2 is the SI unit of G. C. The value of G depends on the distance between the bodies. D. The value of G depends on the masses of the bodies. Correct Answer A, C and D

The correct answer is A, C and D.

  • The ratio of the force of gravitation between two masses, m1 and m2, kept at a distance R on the earth and on the moon, the ratio of masses cannot be same in ratio as gravity on both earth and moon is 1:6. Hence the statement A is incorrect.
  • The SI unit of Gravitational Constant (G) is N m2/kg2. Hence statement B is correct.
  • The Value of G is constant i.e  6.673 × 10–11 N m2 kg–2.
    • It does not depend on anything because it is constant. Its value remains the same everywhere as the value found out here ( Earth) should not vary anywhere in the universe. Hence statements C and D are incorrect.
  • ​The law of gravitation states that the force acting between two masses depends directly on the product of their masses and inversely proportional to the square of their distance between them. It is given by :
    • F = G (m1, m2)/r2
    • G is the universal gravitational constant

Confusion Points We have to find out the incorrect statements which are A, C and D.

In the question given below are two conclusions followed by five statements. You have to choose the correct set of statements that logically satisfies conclusions. Conclusions: I. Some Star are Moon II. Some Sun are not Mars Statements: I. Some Sun are Moon, Some Moon are star and No star is Mars. II. Some Sun are Moon, All Moon are Star and No Star is Mars. III. All Sun are Moon, All Moon are Star and Some Star are Mars. IV. All Sun are Moon, Some Moon are Star and No Star is Mars. V. Some Sun are Moon, Some Moon are Star and No Moon is Mars.
The question below consists of a set of labelled sentences. Out of the four given options, select the most logical order of the sentences to form a coherent paragraph. P- Such a scenario allows for it to have a profound influence on the tides of our oceans, which in turn serves to slow earth’s rotation and hurl the moon further away from us. Q- The gravitational attraction of the moon is also the stabilising factor in a celestial battle between the large bodies of the solar system to throw the planet’s axial obliquity off-balance.  R- The bulk of the moon’s responsibility for impacting upon the planet lies with its gravitation and proximity to the earth. S- The very fact that the moon is here in the first place tells of how fortunate the impact that formed it was. Were it not for that humble collision over 4.5 billion years ago, life on earth would be vastly different today.
The moon looks blood red during a total lunar eclipse because some of the sunlight passes through Earth’s atmosphere to reach the moon. As the white light breaks up while passing through the atmosphere, most of its blue-colored wavelengths are absorbed and scattered. The remaining red wavelengths light up the moon in blood-red color. Which of the following statements do not support the assertion of the above-given statement? I: The moon looks blood red during a total lunar eclipse as the white light breaks up due to the Earth's atmosphere where most of its red-colored wavelengths are absorbed. II: The moon looks blood red during a total lunar eclipse as the earth blocks the white light to travel to the moon.
Which of the following statements is/are false?
1. The value of G is the same as its value on the moon, on Earth.
2. The gravitational force between the centers of two masses of 2 kg placed at a distance of 1m is 26.68 × 10-11 Nm2/kg2.
3. The force is inversely proportional to the square of the distance between the two objects.
4. The force of gravity between two objects doubles when the distance between them is halved.
In this question, the first and last sentences of the passage are numbered 1 and 6. The rest of the passage is split into four parts and named P, Q, R, and S. These four parts are not given in their proper order. Read the sentence and find out which of the four combinations is correct. S1: A force exists between everybody in the universe. P: Normally it is very small but when one of the bodies is a planet, like earth, the force is considerable. Q: It has been investigated by many scientists including Galileo and Newton. R: Everything on or near the surface of the earth is attracted by the mass of the earth. S: This gravitational force depends on the mass of the bodies involved. S6: The greater the mass, the greater is the earth's force of attraction on it. We can call this force of attraction gravity. The Proper sequence should be:
