Question

what is the acceleration of blocks and also find tension? ​

Answer 1

$\huge \fbox \colorbox{lime}{♡ ANSWER ♡}$

Let the acceleration of each block be a and tension in the rope be T.

Horizontal motion : T=ma ..........(1)

Vertical motion : ma=mg−T

∴ ma=mg−ma

$\tt a = \frac{g}{2}$

From (1) we get

$\tt \: t = m \times \frac{g}{2} = \frac{mg}{2}$
