A spherical solid ball of 5 kg mass and radius 5 cm is rotating about an axis passing through its centre with an angular velocity of 50 rad/sec. The kinetic energy of rotation is

Options

A. 12 J
B. 10 J
C. 7 J
D. `6.25 ` J

Explanation

To find the kinetic energy of a rotating spherical solid ball, we can use the formula for rotational kinetic energy:

\[ KE = \frac{1}{2} I \omega^2 \]

where:
- \( KE \) is the kinetic energy,
