To solve the problem of finding the position where the third point charge \( q \) should be placed for it to be in equilibrium between two fixed point charges \( 4Q \) and \( 2Q \) separated by a distance \( x \), follow these steps: ### Step-by-Step Solution 1. **Identify the Forces**: - The third charge \( q \) will experience electrostatic forces due to both \( 4Q \) and \( 2Q \). - Let \( d \) be the distance from \( 4Q \) to \( q \). - Consequently, the distance from \( 2Q \) to \( q \) will be \( x - d \). ...
