The system is released from rest from the positon shown in the diagram. If A and B has mass m and M respectively and all surfaces are smooth, then the normal reaction between A and B is

A

`(2 M)/(M + m)`

B

`(Mmg)/(2 (M + m))`

C

`(Mmg)/((M + m))`

D

zero

Text Solution

Verified by Experts

The correct Answer is:

Comprehension # 1 If net force on a system in a particular direction is zero (say in horizontal direction), we can apply: Sigmam_(R )x_(R )= Sigmam_(L)x_(L) , Sigmam_(R )v_(R )= Sigmam_(L)v_(L) and Sigmam_(R )a_(R ) = Sigmam_(L)a_(L) Here R stands for the masses which are moving towards right and L for the masses towards left, x is displacement, v is velocity and a the acceleration (all with respect to ground).
