A charge `3 mu C` is released at rest from a point P where electric potential is (20 V). Find its kinetic energy when it reaches inifinity.

Explanation

To find the kinetic energy of a charge when it reaches infinity, we can use the principle of conservation of energy. Here’s a step-by-step solution:

### Step 1: Identify the Given Values
- Charge, \( Q = 3 \, \mu C = 3 \times 10^{-6} \, C \)
- Initial electric potential at point P, \( V_P = 20 \, V \)
- Final electric potential at infinity, \( V_{\infty} = 0 \, V \)

### Step 2: Understand the Energy Conservation Principle
