Enter your answer to the tenth's place. Assume that a = 0.2 m and that q = 2.7 x 10-6 C. The two positive charges are separated by a distance 2a. The negative charge is located at (x, y) = (0, 2a). Find the net electric force on each charge. Qualitative Analysis On the graphic above, sketch the direction of the electric force on the requested object(s). Explain why the electric force points in this direction Mathematical Analysis

Explanation / Answer

Part 1)

First we need the distance between q and -2q...

From the Pythagorean Theorem...

r2 = (.3)2 + (.6)2 = .45

We also need the angle...

tan(angle) = 2a/a

angle = 63.4o

Then the force is from F = kqq/r2

F = (9 X 109)(2)(6.3 X 10-6)2/(.45)

F = 1.5876 N

The y component of each of the +q charges is the same and will add, so

Fy = 2(1.5876)(sin 63.4)

Fy = 2.84 N

Part 2)

No calculation needed. The x components will cancel. Each of the q's will equall pull left and right on the -2q thus canceling out. Fx = 0N
