Question

A -6μC charge exerts an attractive force of 65N on a second charge that is 5cm away. What is the magnitude of the second charge?
Options
A 6×10⁻⁶ C
B 9.3×10⁻⁶ C
C 5.3×10⁻⁶ C
D 3×10⁻⁶ C
Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

|q₂| = Fr²/(k|q₁|) = 65(0.05)²/(9×10⁹×6×10⁻⁶) = 3.0×10⁻⁶ C

Hint

Apply Coulomb's Law and solve for the unknown charge magnitude.
