A smooth wedge moves to the right on the horizontal plane with an acceleration a. A mass m is attached to the wedge through a thread as shown in the figure. The thread is parallel to the incline.
Which among the following equations is/are correct :-
Options:(select one or more)
Answer:
A
Solution:
(A) Ground frame: the mass moves with the wedge and the tension (along the incline) has a component along the motion - non-zero work, correct.
(B) Wedge frame: the mass is stationary - zero work. (C) No pseudo force exists in the inertial ground frame. (D) In the wedge frame there is no displacement. Ans. (A)
