Given, mass $m$ = 500 g

Height $h$ = 5 m

When the body reaches the maximum height above the ground, it will have the maximum gravitational potential energy.

The work done by the bow on arrow is equal to the maximum gravitational potential energy stored in it, which is equal to "m $\times$ g $\times$ h"

$m \times g \times h = \frac{500}{1000} \times 10 \times 5 = 25 J$
