Two thin isolated concentric conducting spheres of radii

Question

Solve the all parts of given question:

Question: Two thin, isolated, concentric conducting spheres of radii 2.60 cm and 10.10 cm, have net charges of 46.50 nC and 18.00 nC, respectively. What is the electric field at 1.690 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.

Part A: What is the electric potential at 1.690 cm from the center of the spheres?

Part B: What is the electric field at 5.975 cm from the center of the spheres?

Part C: What is the electric potential at 5.975 cm from the center of the spheres?

Part D: What is the electric field at 11.790 cm from the center of the spheres?

Part E: What is the electric potential at 11.79 cm from the center of the spheres?
