Two charges `3xx10^(-8) C and -2xx10^(-8)C ` are located 15 cm apart. At what point on the line joining the two charges is the electric potential zero ? Take the potential at infinity to be zero.

Explanation

To find the point on the line joining two charges where the electric potential is zero, we need to use the principle that the total electric potential at that point due to both charges must sum to zero.

Given:
- Charge \( q_1 = 3 \times 10^{-8} \, \text{C} \)
- Charge \( q_2 = -2 \times 10^{-8} \, \text{C} \)
- Distance between charges \( d = 15 \, \text{cm} = 0.15 \, \text{m} \)

Let's denote the point where the electric potential is zero as \( P \). Assume \( P \) is at a distance \( x \) from \( q_1 \) and \( (0.15 - x) \) from \( q_2 \).
