Two point charge Q and 4Q are fixed at a distance of 12cm from each other. Sketch lines of force and locate the neutral point, if any .

Explanation

### Step-by-Step Solution

1. **Identify the Charges and Distance**:
We have two point charges, \( Q \) and \( 4Q \), fixed at a distance of 12 cm from each other.

2. **Understanding Electric Field Direction**:
Since both charges are positive, the electric field lines will originate from both charges and point away from them. The electric field due to charge \( Q \) will point away from \( Q \), and the electric field due to charge \( 4Q \) will point away from \( 4Q \).
