Suppose the surface is frictionless and a constant force P is applied from left to right to the end face of A. which of the following statements are correct :

A

The acceleration of the system is `5P//m`

B

The resultant force acting on each cube is `P//5`

C

The force exerted by C and D is `2P//5`

D

The acceleration of the cube `D is P/5 m`

Text Solution
