Electric field inside an uniformly charges non conducting sphere

Q. Intensity of electric field inside a uniformly charged conducting hollow sphere is :

Q. For a uniformly charged non conducting sphere, the electric field from its center:

Q. A non-conducting sphere with a cavity has volume charge density $\rho$. $O_1$ and $O_2$ represent the two centres as shown. The electric field inside the cavity is $E_0$. Now, an equal and opposite charge is given uniformly to the sphere on its outer surface. The magnitude of electric field inside the cavity becomes

Q. Calculate electric field intensity due to uniformly charged non-conducting sphere:
(a) outside the sphere
(b) at the surface of sphere
(c)inside the sphere
(d) at the centre of the sphere
Plot at graph between electric Held intensity and distance.

Q. What is the electric field intensity at the centre of the uniformly charged non-conducting sphere?
