Aspherical cavity of radius 7.00 cm is at the center of a metal sphere of radius 17.5 cm . a point charge 6.20 μc rests at the very center of the cavity, whereas the metal conductor carries no net charge. part a part complete part b part complete part c determine the electric field at a point 60.0 cm from the center.

The electric field at a point 60.0 cm from the centre is

Explanation:

Given:

Since the solid sphere is Metallic and we know that there should be no charge inside a metal due to property. So the Equal magnitude but opposite in sign of the charge will be at that inner surface of the cavity and finally to the outer surface of the metal sphere.

Let E be the electric field due to this at the 60 cm from the centre given by

The direction of electric Field is radially outwards.
