A particle of mass m is at rest in a train moving with constant velocity with respect to ground. Now the particle is accelerated by a constant force F_(0)acting along the direction of motion of train for time t_(0). A girl in the train and a boy on the ground measure thework done by this force. Which of the following are incorrect?

1.	A particle of mass m is at rest in a train moving with constant velocity with respect to ground. Now the particle is accelerated by a constant force F_(0)acting along the direction of motion of train for time t_(0). A girl in the train and a boy on the ground measure thework done by this force. Which of the following are incorrect?
Answer» Both will MEASURE the same work Boy will measure higher value than the girl Girl will measure higher value than the boy Data are INSUFFICIENT for the MEASUREMENT of work ' done by the force `F_(0)` Answer :A::C
