Question

Q=3C, W=12J Find out P. D across two points​

Answer 1

Explanation:

Use the formula ΔV=Ed Δ V = E d to calculate the potential difference between the two points. Since the direction of motion (up) is opposite to the direction of the electric field (down) the answer is positive. The potential difference from charge B to A is ΔV=50V Δ V = 50 V .
