Solve the all parts of given question:

Question: A solid conducting sphere of radius 2.00 cm has a charge 17.00 µC. A conducting spherical shell of inner radius 4.00 cm and outer radius 5.00 cm is concentric with the solid sphere and has a total charge of -3.00 µC. (Take radially outward as the positive direction).

Part A: Find the electric field at r = 1.00 cm from the center of this charge configuration.

MN/C

Part B: Find the electric field at r = 3.00 cm from the center of this charge configuration.

MN/C

Part C: Find the electric field at r = 4.50 cm from the center of this charge configuration.

MN/C

Part D: Find the electric field at r = 7.00 cm from the center of this charge configuration.

MN/C
