Two parallel plate air capacitors have their plate areas 100 and 500 cm^(2) respectively. If they have the same charge and potential and the distance between the plates of the first capacitor of 0.5 mm, what is the distance between the plates of second capacitor ?

Two metal spheres, one of radius R and the other of radius 2R, both have the same surface charge density s. They are brought in contact and separated. What will be new surface charge densities on them?

Two identical plane metallic surfaces A and B are kept parallel to each other in air separated by a distance of 10 cm as shown in Figure. Surface A is given a positive Potential of 10 V and outer surface of B is earthed. What is the magnitude and directions of uniform electric field between points Y and Z?
