A block of mass M is pulled along horizontal frictionless surface by a rope of mass m. Force p is applied at one end of rope Fig.  The force which

the rope exerts on the block is

a
P(M−m)
b
PM(m+M)
c
PM(m+M)
d
PM(M−m)

detailed solution

Correct option is C

Let o be the common acceleration of the system. HereT =M o for blockP -T =m o for rope∴P - M a=ma or P = a(M+m)or a=P(M+m)Now T=MP(M+m)
