Option 4 : The object will move with constant velocity.

CONCEPT:

  • Newton’s Third Law states that for every action there is an equal and opposite reaction.
  • Newton’s first law states that an object that remains in uniform motion will remain in uniform motion unless it is acted upon by an external force.
  • Force: The interaction which after applying on a body changes or try to change the state of rest or state of motion is called force. 

Force (F) = Mass (m) × acceleration (a)

EXPLANATION:

  • If the net resultant force is zero, then the acceleration of the body will be zero, and the state of motion is not changed and hence the object will move with constant velocity. So option 4 is correct.

These four parts are not given in their proper order. Read the sentence/ passage and find out which of the four combinations is correct. 1. Jupiter has 2.5 times more mass than all the other planets of the solar system combined and is 11 times as large as Earth in diameter. P. Jupiter is so large that scientists believe it almost became a star: as the gases and dust contracted to the form the planet, Q. But there was not enough mass available to create the temperature needed to start a fusion reaction such as that of the Sun. R. Thus, Jupiter has been cooling down ever since.  S. gravitational forces created tremendous pressure and the temperature inside the core—as high as tens of thousands of degrees. 6. Even so, Jupiter radiates about as much heat as it receives from the Sun.?
