A monkey of mass mkg slides down a light rope attached to a fixed spring balance, with an acceleration a. The reading of the spring balance is W kg. [g = acceleration due to gravity]

A

`m=(wg)/(g-1)`

B

`m=w(1+(1)/(g))`

C

the force 32of friction exerted by the rope on the monkey is m (g –a) newton

D

even though there is no chhange in momentum, there is a change in direction. Hence, it has an acceleration.
