Two concentric conducting shells a and b are of radii R and 2R. A charge +q is centred at their center. Shell b is then earthed and a is given charge q. Find the charge on outer surfaces oboth shells.
Ans) THE charge on outer surface of A will be 2q and outer surface of B will be zero due to earthing charge on b will flow to earth.

A copper rod which is 1 centimetre in diameter carries a current of 5 amps. The current is distributed uniformly over the rod. The magnetic field half way among the axis o
HYSTERESIS LOOP: A ferromagnetic material retains some magnetism after the magnetising force is removed. The BH curve (O to Q) will therefore only be followed once, on initial
The earth "spins" (rotates) on its axis based on the action of the materials that accreted to form it, and also on any large collisions it might have undergone. Like the one in the
