Concept

Problem: The point charge at the bottom of the figure is Q = +17 nC, and the curve is a circular arc. What is the magnitude of the force on the charge Q due to the other point charges shown? (k=1/4π ℇ0 = 8.99x109 N•m2/C2)

FREE Expert Solution

We use Coulomb's law in this problem given as:

F=kq1q2r2, where F is electric force, k is Coulomb's constant, and r is the separation between charges q1 and q2.

From Coulomb's law, the force due to charge 2.0 nC on Q is:

F2Q=kQ(2.0×10-9)r2cosθ
