Question 32 WAEC_MODEL_QUESTIONS_VOL1 • 2019 • PHYSICS • objective

Two point charges are placed on a straight line. A charge +8 μC is at the origin and a charge -2 μC is 30 cm to its right. Determine (a) the position on the line where the net electric field is zero, and (b) the electric potential at that point. Express the position as a distance from the +8 μC charge and give the potential in volts.

Answer Options

A. 0.60 m from the +8 µC charge; 4.3×10^4 V
Correct Answer B. 0.60 m from the +8 µC charge; 6.0×10^4 V
C. 0.45 m from the +8 µC charge; 5.2×10^4 V
