Two charges + q and - q , each 1 C are arranged as shown in the figure. If x=2 ~cm and y=3 ~cm then potential difference (V_A-V_B ) is
Options
- A5.4 10^2 ~V
- B5.4 10^5 ~V
- C5.2 10^2 ~V
- D2.7 10^5 ~V
Correct answer
D. 2.7 10^5 ~V
Step-by-step solution
Distance between two charge, d=2 x+y =2 2+3=7 10⁻² ~m Potential at A, V_A= 1 4 ₀ q d =9 10^9 1 10⁻⁶ 7 10⁻² Potential at B, V_B= 1 4 ₀ -q d =-9 10^9 10⁻⁶ 7 10⁻⁶ V_A-V_B=2 9 10⁻⁹ 10⁻⁶ 7 10⁻⁶ =2.7 10^5 ~V
