Question

Positive electric charge Q is distributed uniformly throughout the volume of an insulating sphere with radius R.From the expression for E=kQ/r2 for r>R and E=kQr/R3 for r

Only need C & D. It asks for specfic points that I don't know how to find. I just know the general shape of the graph.

Answer 1

The electric field due to the charge distributed throughout the volume of an insulating sphere can be determined at points both inside and outside the sphere using specific expressions.

Step-by-step explanation:

The electric field due to the charge distributed throughout the volume of an insulating sphere can be determined at points both inside and outside the sphere. For points inside the sphere, where r is less than the radius R, the electric field can be found using the expression E=kQ/r^2. For points outside the sphere, where r is greater than R, the electric field can be found using the expression E=kQr/R^3. These expressions represent the general shape of the graph of the electric field.
