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.
The effects of back emf on circuit current: In proving the time constant, it was stated that, at the instant the switch is closed, the current (I) is zero. This is because, at
A rigid object is a body with a exact and unchanged size and shape i.e. a body is said to be rigid if the distance among any two particles of the body remains invariant.
