A point charge of -2.10 �C is located in the center of a spherical cavity of radius 6.54 cm inside an insulating spherical charged solid. The charge density in the solid is 7.36 x 10-4 C/m3. Calculate the electric field inside the solid at a distance of 9.48 cm from the center of the cavity. (magnitude and direction)

Explanation:

We are given that

We have to find the electric field inside the solid at distance of 9.48 cm from the center of the cavity.

Volumetric charge density,

Charge on spherical solid=

Electric field =Electric field due to spherical charge solid +electric field due to charge at center

Where

Where  negative sign indicates that the direction of electric field is inward.

double the distance = divide strength by 4

spare some change and give it to the poor
