Question
Two thin, isolated, concentric conducting spheres of radii 0.80 cm and 5.90cm, have net charges of 34.00 nC and 12.50 nC, respectively. What is the electric field at 0.400 cm from the center of the spheres? Use the sign of the field to indicate direction, thus a positive electric field would point away from the center of the spheres.
0.0 V/m
What is the electric potential at 0.400 cm from the center of the spheres?
What is the electric field at 3.350 cm from the center of the spheres?
What is the electric potential at 3.350 cm from the center of the spheres?
What is the electric field at 6.420 cm from the center of the spheres? What is the electric potential at 3.350 cm from the center of the spheres?
What is the electric potential at 6.42 cm from the center of the spheres?
Explanation / Answer
electric field at point 0.4=0
potential=kQ1/0.4
electric field at point 3.35=kQ1/(3.35)2
potential=k(Q1+Q2)/3.35
electric field at point 6.42=k(Q1+Q2)/6.422
electric potential =k(Q1+Q2)/6.42
