Q3 (35P). A spherical insulator shell with radius r1=1.0 cm is covered with a larger spherical insulator shell with radius r2=D2.5 cm and they are concentric. The thickness of both shells can be ignored. The charges of both shells are distributed uniformly over their surfaces and their charges are q1=-5.0x10-5 C and q2=6.0x10-6 C for inner and outer shells, respectively. You may take the electric potential to be zero at an infinite distance from both shells. a) Calculate the electric potential because of these two shells at distances R= 0, R= 2.0 cm and R=5.0 cm. b) Calculate the potential difference between two shells' surfaces? Determine the shell having lower potential and comment the physical meaning. Q3 (35P).
