9-36. Two negative charges have locations as shown in the Figure. Charge
q1 is -3.6X10-8 C; charge q2
is -5.2X10-8 C. What is the electric field (magnitude
and direction) at (a) point A? (b) point B?
ACCUMULATED SOLUTION
Correct
The magnitude of the field E1
due to q1 at the point A is:
(A) |E1|
= k|q1|/r1
(B) |E1|
= k|q1|/r12
(C)
|E1| = k|q1|r12
