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.

consider an experiment where you drop an object. brieffly decribe your proposed experiment. what is the indepentent variable and dependent.
Regard as a Cartesian coordinate system on which the electric potential due to an unspecified distribution of charge is a function of x only. A graph is made of V(x) vs x. The elec
Q. The minimum wavelength of X-rays produced in a Coolidge tube is 0.05 nm. Find the operating voltage of the Coolidge tube. λmin = 12400 A 0 / V = 0.5 X 10 -10 m Theref
Q State Lenz's law. Lenz's law declares that the induced current produced in a circuit always flows in such a direction that it opposes the change or cause that produces it.
