Consider a finite insulated, uncharged conductor placed near a finite positively
Consider a finite insulated, uncharged conductor placed near a finite positively charged conductor. The uncharged body must have a potential:
- A. less than the charged conductor and more than at infinity.
- B. more than the charged conductor and less than at infinity.
- C. more than the charged conductor and more than at infinity.
- D. less than the charged conductor and less than at infinity.
Step-by-step solution
The positively charged conductor has a positive potential relative to infinity. By induction, the uncharged conductor acquires a positive potential but lower than that of the charged conductor because it is farther away, and its potential is still above zero (infinity). Thus, its potential lies between that of the charged conductor and infinity.
