It is given that d>>aandd>>b so that charge distribution on both the sphere remains spherically symmetric. Assume that a charge +q is given to the sphere of radius a and −q is given to the sphere of radius b. (i) Write the electrostatic energy (U) of the system and calculate the capacitance of the system using the expression of U.

(i) Write the electrostatic energy (U) of the system and calculate the capacitance of the system using the expression of U.

find the final charge on each sphere. respectively. These two spheres are connected with a cell of emf V volts as show in. When the switch is closed There are two spheres of radii R and 2R having charges Q and Q/2
