A block of mass M is pulled along a horizontal frictionless 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 .

Text Solution

Verified by Experts


IF a is the acceleration produced in the system then
`a=P/((M+m))`…….(i)
the force exerted by the rope of the block is
`F=ma= (MP)/((M+m))`
