From the equilibrium of pulley P1 which is massless we can see that tension in upper string is is 50 N. Similarly, from equilibrium of P2 we can see that tension in lower string will be 25 N.

Q. In the diagram shown in figure, both pulleys and strings are massless. The acceleration of 2 kg block is

$2.5 m s^{- 2} (↑)$

$5 m s^{- 2} (↑)$

$7.5 m s^{- 2} (↓)$

$10 m s^{- 2} (↑)$

From the equilibrium of pulley $P_{1}$ which is massless we can see that tension in upper string is is 50 N. Similarly, from equilibrium of $P_{2}$ we can see that tension in lower string will be 25 N.
