Question

Field due to cavity in a conducting sphere

Answer 1

Answer: The electric field inside the cavity is going to be the superposition of the field due to the uncut sphere plus the field due to a sphere the size of the cavity with a uniform charge density of . The key to solve this problem is to calculate the electric field of each sphere in a different coordinate systems.

Explanation:

Answer 2

Explanation:

significance notice that in the region ,the electric field due to a charge q placed on an isolated conducting sphere of radius R is identical to the electric field of a point charge q located at the centre of the sphere.
