Answer:
Information about masses of blocks is not given explicitly in the question. Hence I assume masses are not same.
Since Blocks A and C are pulled with constant speed, tension in the strings are due to weight of blocks only.
Tensions are marked in figure.
we write Newton's law for block-B, based on the forces acting on it.
.................................(1)where a is acceleration of block-B
By substituting the tensions in eqn.(1), we get 
...................(2)
...................(2)if masses are identically same, then we get 
...............(3)
...............(3)where
