the center of two identical small conducting sphere are 1 m apart they carry charges of opposite kind and attract each other with a force F. when they are connected by a conducting thin wire they repel each other with a force F/3 what is the ratio of magnitude of charge carried by the sphere initially
Answers
Answer:
C
3:1
The conducting sphere =1m, Force =F (Attraction)
when they repel =
3
F
ratio of magnitude of charges carried by the sphere initially =
F=
