Questions
Two metallic spheres of radii 1 cm and 3 cm are given charges of , respectively. If these are connected by a conducting wire, the final charge on the bigger sphere is :
detailed solution
Correct option is D
Total charge = -1 x 10-2 C + 5 x 10-2 C = 4 x 10-2 CAs, q1 : q2=r1 : r2=1 : 3So, q2=34 x 4 x 10-2C=3 x 10-2CTalk to our academic expert!
