Question

Three charges Q1 = 6.0 mC, Q2 = -6.0 mC and Q3 = 4.0 mC are located at -0.6i, 0.6i and +0.8j. Find the net force on Q3 charge.
Options
A 0.26i N
Correct Answer
B 0.26j N
C 0.6i N
D 0.6j N
Correct Answer

Option A is the correct answer.

Detailed Explanation

Adding the Coulomb force vectors from Q1 and Q2 acting on Q3 (using the given coordinates) and resolving into components gives a net force along the i-direction of about 0.26 N.

Hint

Resolve each Coulomb force on Q3 into x and y components before summing.
