A block B of mass M is suspended from a cord of length `l` attached to a cart A of mass M as shown in the figure. The horizontal surface on which the cart moves is smooth. Initially both the cart and the block are at rest in the position shown. Now B is released. Take `M=m=2kg, theta=45^(@) and g=10m//s^(2)`.

The acceleration of the cart immediately after the system is released from rest is

A

`(1)/(sqrt(2))m//s^(2)`

B

`(10)/(3)m//s^(2)`

C

`(10)/(3sqrt(2))m//s^(2)`

D

`5m//s^(2)`
