A batsman hits the ball of mass 250 g with his bat and the ball leave...
Given:
- Mass of the ball (m) = 250 g = 0.25 kg
- Speed of the ball (v) = 10 m/s

To find:
The work done by the bat on the ball.

Formula:
The work done (W) is given by the formula:
W = 0.5 * m * v^2

Calculation:
Substituting the given values into the formula:
W = 0.5 * 0.25 kg * (10 m/s)^2
W = 0.5 * 0.25 kg * 100 m^2/s^2
W = 0.125 kg * 100 m^2/s^2
W = 12.5 Nm

Answer:
The work done by the bat on the ball is 12.5 J (Joules).
Therefore, option B is correct.
