Question

If I consider two metallic charged spheres whose radii are 20cm
and 10cm respectively, each having 150 microcoulomb positive charge
What is their common potential after they are connected by a
conducting wire ????

Chanti · Answer

total charge Q = 2*150*10-6C
C1 + C2 = 0 30/9*109 F
V= (300*10-6 *9*109 )/0 03 V
V=9*106 volt
