17. If two bodies of different masses, initially at rest, are acted upon by the same force for the same time, then the both bodies acquire the same: A.Velocity B.Momentum C.Acceleration D.Kinetic energy
Answer: Option B Solution: Since the Force and the duration of time for which it acted are same, the product of force and time will be the same for both. Since Force×time gives change in momentum of a body, and they had 0 momentum initially, their final momenta will be same.
