Physics · JEE | Electric Charges and Fields

Based on Figure 1.11 depicting two point charges \( q_1 = +10^{-8} \text{ C} \) and \( q_2 = -10^{-8} \text{ C} \) separated by \( 0.1 \text{ m} \), what is the magnitude of the electric field at point C situated at equal distance \( 0.1 \text{ m} \) from both charges?

1. A
   \( 7.2 \times 10^4 \text{ N C}^{-1} \)
2. B
   \( 3.6 \times 10^4 \text{ N C}^{-1} \)
3. C
   \( 9 \times 10^3 \text{ N C}^{-1} \)
4. D
   \( 4 \times 10^3 \text{ N C}^{-1} \)
