AIIMS 2019 Physics Centripetal Acceleration MCQ Question

The acceleration of an electron moving in a circular path can be calculated using the formula for centripetal acceleration, $a = \frac{v^2}{r}$, where $v$ is the speed and $r$ is the radius. Substituting the given values, $a = \frac{(4 \, \text{m/s})^2}{2 \, \text{m}} = \frac{16 \, \text{m}^2/\text{s}^2}{2 \, \text{m}} = 8 \, \text{m/s}^2$, confirming option (A) as correct. Options (B), (C), and (D) are incorrect as they do not match the calculated centripetal acceleration based on the provided speed and radius.
