Question
Two point charges q1 = +2.26 nC and q2 = -2qare located along the x-axis as shown in the diagram below. The distance between the two charges is d = 1.45 m.
Two point charges q1 = +2.26 nC and q2 = -2qare located along the x-axis as shown in the diagram below. The distance between the two charges is d = 1.45 m. Which of the following graphs correctly represents the total electric potential versus x for the region ?2.50 m At what location A between the two charges on the x-axis will the electric potential be zero?
Explanation / Answer
r1/r2=q1/q2=1.13
=>r1/(r1+r2)=1.13/2.13
=>r1=1.13*1.45/2.13;
=>r1=76.91cm from charge q1
