A nonconducting sphere of radius R is filled with uniform volume charge density `-rho`. The center of this sphere is displaced from the origin by `vecd`. The electric field `vecE` at any point P having position vector inside the sphere is

The electric field intensity |vecE| at any point inside a charged sphere of radius r is

A sphere of charge of radius R has uniform volume charge density. The electric field due to the sphere of charge at a point

A solid non-conducting sphere of radius R is charged with a uniform volume charge density rho . Inside the sphere a cavity of radius r is made as shown in the figure. The distance between the centres of the sphere and the cavity is a. An electron of charge 'e' and mass 'm' is kept at point P inside the cavity at angle theta = 45^(@) as shown. If at t = 0 this electron is released from point P, calculate the time it will take to touch the sphere on inner wall of cavity again.

A sphere of radius R has a uniform volume density rho . A spherical cavity of radius b, whose center lies at veca , is removed from the sphere. i. Find the electric field at any point inside the spherical cavity. ii. Find the electric field outside the cavity (a) at points inside the large sphere but outside the cavity and (b) at points outside the large sphere.
