Question

A block is placed on the horizontal plane. write the forces act on the block ​

Answer 1

plane and between block and plane, respectively, then work done by the applied force is given by : ... work done against frictions acting on plank and block + energy in the elastic string.

Answer 2

Answer:

When a plank is moved, the string is under tension. Work done by force F tries to neutralise the frictional force of plank(FP ) and elongation of the string due to non-sliding of the block due to its friction(FB ).

Hence, work done by F will be equal to work done against friction acting on plank + energy in the elastic string due to work done by friction acting on block.
