Question

I. A positive charge and a negative charge are placed in the x-y plane. One charge Q1= 10-8 C is placed at a point x=-4 cm y=0, the second Q2 = -10-8 C is placed at a point x=+4 cm y=0. See figure. Answer the following questions. 2. Find the force, magnitude and direction, on a -10-8 Coulomb charge placed at the origin a) 1.4x10-4 towards Q1 and away from Q2 b) 5.63x10-4 towards Q2 and away from Q1 c) 1.13x10-3 towards Q1 and away from Q2 d) 2.81x10-4 from right to left e) 2.81x10-4 from left to right

Explanation / Answer

E=2Kq/r^2 =1.125*10^5 N
