Two particles of masses 2 kg and 3 kg are at rest and are separated by 10 m. If they move towards each other under the mutual force of attraction, they would meet at _____

Two particles of masses 2 kg and 3 kg are at rest and are separated by 10 m. If they move towards each other under the mutual force of attraction, they would meet at _____ Correct Answer 6 m from 4 kg body

The two bodies would meet at their centre of mass. Sum of masses = 2 + 3 = 5 kg Let us consider the 2 kg body as a reference; The centre of mass from the 2 kg body =(3 x 10) / 5 = 6 m.

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:
