A block of mass 2 m is pulled along a horizontal frictionless surface by a rope of mass m as shown in the figure given above. What force is exerted by the rope on the block ?

`(F)/(3)`

`(F)/(2)`

`(2F)/(2)`

Text Solution

Verified by Experts

The correct Answer is:

Since the surface is frictionless, force exerted by the rope on the block is the pulling force i.e., F.
