QUESTION: Problem 28P
What are the magnitude and direction of the electric field at a point midway between a –8.0 μC and a +7.0 μC charge 8.0 cm apart? Assume no other charges are nearby.
ANSWER:
Solution 28P
Step 1 of 2:
We need to find the direction and magnitude of the electric field at the point midway between two charges kept at a distance r.
The first charge Q1 = -8.0 μC = -8 x 10-6 C
The second charge Q2 = +7.0 μC = 7 x 10-6 C
The distance between the two charges r = 8 cm = 0.08 m
The constant k = 9.0 x 109 N.m2/C2
