Question

Part a) Charge on a metal conducting sphere is 10 nC. The outer radius of the sphere is 0.5m. The electric field inside the sphere????

part b) How much work done by the electric filed on a charge of 2C that travels from infinity to a point of 5V?

Answer 1

The electric field inside a conducting sphere is zero, and no work is done within it. The work done by an electric field on a 2C charge brought from infinity to a point of 5V potential is 10 joules.

Step-by-step explanation:

This is related to the electric fields generated by charges in and around conducting spheres, and the work done by electric fields. To answer the student's question: Part A: The electric field inside a conducting sphere is zero, irrespective of the charge present on the sphere. When the sphere is conducting, charges redistribute themselves on the outer surface of the sphere, and the electric field inside the conductor is zero due to electrostatic shielding. Part B: To calculate the work done by the electric field on a charge of 2C that is moved from infinity to a point of potential 5V, you can use the formula: W = qV. where W is the work done by the electric field, q is the charge, and V is the electric potential. Substituting the given values: W = (2 C)(5 V) = 10 J. So 10 joules of work is done by the electric field.
