PHY 102 Electrostatics: Electric Charge and Coulomb's Law Objective Question
Take CBT

Question

Calculate the separation distance between two charges of +0.0003 C and -0.0001 C having an electrostatic potential energy of -450 J (κ = 8.99 × 10⁹ J·m·C⁻²).
Options
A 0.300 m
B 0.599 m
Correct Answer
C 1.200 m
D 2.450 m
Correct Answer

Option B is the correct answer.

Detailed Explanation

d = κ * q1 * q2 / Eel = (8.99 × 10⁹ * 0.0003 * -0.0001) / (-450) = 0.599 m.
