There are two spheres of radii R and 2R having charges Q and Q/2
Two conducting sphere of radii a and b are placed at separation d. 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.

A parallel plate capacitor is connected across a battery of emf V as shown in figure. The plates of the capacitor have area A and separation between the plates is d. Now switch S is clossed to connect the capacitors with battery. Now the distance between the plates is slowely reduced to d/2. Cacluclate the work done by the external agent in the process.
