A mass $M$ is lowered with the help of a string by a distance $h$ at a constant acceleration $\frac{g}{2}$ . The work done by the string will be

Answer:

Solution:

Tension in the string

$T = M (g - a) = M (g - \frac{g}{2}) = \frac{M g}{2}$

$W = F o r c e \times d i s p l a c e m e n t$

$= - \frac{M g h}{2}$
