Concept

Problem: What is the force F on the 1.0 nC charge in (Figure 1)?A) Determine the magnitude of the force F.B) Determine the direction of the force F.

FREE Expert Solution

The electric force from Coulomb's law:

F=kq1q2r2, where k is Coulomb's constant and r is the distance between two charges q1 and q2.

The net electric force is expressed as:

Fnet=Fx2+Fy2, where Fx and Fy are the x and y components of electric force. 

Direction:

θ=tan-1(FyFx)

A. 

In this problem, let's consider the direction to the right to be positive x-axis and upwards to be positive y-axis. 

The force F1 due to charge q1 on charge q2 is given by:
