Name any three animals whose eggs are without calcareous shells.

In a spherical capacitor,-we have two concentric spherical shells, the inner one carrying a charge Q and outer one carrying a charge of -Q . If the inner shell is displaced from the center without touching the outer shell :

A semi cylindrical shell with negligible thickness oscillates without slipping on a horizontal surface. The time period of small oscillations is R

A spherical shell of radius R has two holes A and B through which a ring having charge +q passes through without touching the shell. The flux through spherical shell is (q)/(3epsilon_(0)) . Find the radius of the ring:

When a sphere, ring, disc and a spherical shell are coming down on an inclined plane, rolling without slipping, which will reach the ground first?

Three concentric conducting spherical shells carry charges as : +4Q on the inner shell, -2Q on the middle shell and -5Q on the outer shell. The charge on the inner surface of the outer shell is
