Question

Solve the all parts of given question:

Question: A point charge of -2.03C is located in the center of a spherical cavity of radius 6.55cm inside an insulating spherical charged solid. The charge density in the solid is 7.35×10⁴ C/m³.

Part A: Calculate the magnitude of the electric field inside the solid at a distance of 9.49cm from the center of the cavity.

Part B: Find the direction of the electric field inside the solid at a distance of 9.49cm from the center of the cavity.

I need help to find the direction of the electric field inside the solid.
