Question

Choose the correct answer A block of mass 'M' is pulled along a horizontal frictional surface by a rope of mass 'm' if a force 'p' is applied at the free end of the rope.The force exerted by the rope on the block is A)p×m\m+M B)p C)p×M\m×M D)p×m\M-m

Answer 1

Acceleration of system =PM+m=PM+m

Force on the block= Mass of block ×× acceleration of system

=M×PM+m=M×PM+m

=MPM+m
