Two charges `+- 10 muC` are placed `5xx10^(-3) m` apart. Determine the electric field at a point `Q, 0*15m` away from O, on a line passing through O and normal to the axis of the dipole.

Explanation

To solve the problem, we need to determine the electric field at point Q, which is located 0.15 m away from the midpoint O of the dipole consisting of two charges of +10 µC and -10 µC, separated by a distance of 5 mm (5 x 10^(-3) m).

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Charge, \( Q = 10 \, \mu C = 10 \times 10^{-6} \, C \)
- Distance between charges, \( A = 5 \times 10^{-3} \, m \)
- Distance from the midpoint O to point Q, \( r = 0.15 \, m = 15 \times 10^{-2} \, m \)
