Question

A positively charged conductor

• A. Is always at +ve potential
• B. Is always at zero potential
• C. Is always at negative potential
• D. May be at +ve, zero or -ve potential

Answer 1

Answer: (D)

1. The electric potential due to a charge at a distance r is given by; $V=\frac{1}{4\pi {\epsilon }_0}\frac{q}{r}$
2. ​If the conductor is charged positively; the electric potential will be; $\frac{1}{4\pi {\epsilon }_0}\frac{+q}{r}$
3. Thus, the charged co9nductor is always at positive potential.

Thus,

Option a) Is always at +ve potential is the correct option.
