Concept

Problem: A point charge +3q is located at the origin, and a point charge -q is located on the x-axis at d = 0.5 m. At what location on the x-axis will a third charge q0 experience no net force from the other two charges?

FREE Expert Solution

Coulomb's law:

F=kq1q2r2

Applying Coulomb's law between 3q and q0:

F1=k(3q)(q0)x2=k3qq0x2

Applying Coulomb's law between -q and q0:

F2=k(-q)(q0)(x-D)2=-kqq0(x-0.5)2
