A particle of mass m and positive charge q is released from point A. Its speed is found to be v when it passes through a point B. which of the two points is at higher potential ? What is the potential difference between the points?

Explanation

To solve the problem, we will use the concepts of electric potential energy and kinetic energy.

### Step-by-Step Solution:

1. **Understanding the Initial Conditions**:
- A particle of mass \( m \) and positive charge \( q \) is released from point A.
- The initial speed at point A is \( 0 \) (since it is released).
- The speed at point B is \( v \).
