Question 33 NECO_MODEL_QUESTIONS_VOL1 • 2025 • PHYSICS • objective

Two point charges are placed on a straight line 20 cm apart. A charge \(q_1 = +8\ \mu\text{C}\) is at the origin and a charge \(q_2 = -2\ \mu\text{C}\) is at \(x = 20\ \text{cm}\). (i) Find the position on the line between the charges where the net electric field is zero, giving the distance from \(q_1\). (ii) Calculate the electric potential at that point, taking the potential to be zero at infinity.

Answer Options

Correct Answer A. x = 0.133 m, V = 2.7×10^5 V

C. x = 0.200 m, V = 3.5×10^5 V
D. x = 0.067 m, V = 1.3×10^5 V
Correct Answer
A
Correct Option:
x = 0.133 m, V = 2.7×10^5 V
