Question

An object of mass 10 gram is sliding with a constant velocity of 10 metre per second on a frictionless horizontal table find the force required to keep the moving object with the same velocity

Answer 1

Actually, No Force required to keep it moving with that velocity.

as according to 1st Law of Newton: every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.

And in this case there is no external force on the body as friction is absent.

So the Body will keep sliding Forever.

And if you are confused because of the mass then it's purpose was that only.

The mass will be used only if the value of friction constant is given.
