A metal sphere with radius ra = 1.30 cm is supported on an insulating stand at the center of a hollow, metal, spherical shell with radius rb = 9.00 cm . Charge +q is put on the inner sphere and charge −q on the outer spherical shell. The magnitude of q is chosen to make the potential difference between the spheres 430 V , with the inner sphere at higher potential.

Part A

Calculate q.

Part B

Are the electric field lines and equipotential surfaces mutually perpendicular?

PART C

Are the equipotential surfaces closer together when the magnitude of E⃗  is largest?
