Both the blocks as shown in figure are given together a horizontal velocity towards right. The acceleration of the centre of mass of the system of block is `(m_(A) = 2m_(B) = 2kg)`.

(A)zero (B)`5//3 m//s^(2)` (C)`7//3 m//s^(2)` (D)`2 m//s^(2)`

Options

A. zero
B. `5//3 m//s^(2)`
C. `7//3 m//s^(2)`
D. `2 m//s^(2)`
