Q99 / 120 · VITEEE 2012 · Physics
A hollow conducting sphere is placed in an electric field produced by a point charg placed at $\mathrm{P}$ as shown in figure. Let $\mathrm{V}_{\mathrm{A}}, \mathrm{V}_{\mathrm{B}}, \mathrm{V}_{\mathrm{C}}$ be the potentials at points $\mathrm{A}, \mathrm{B}$ and $\mathrm{C}$ respectively. Then


- A$\mathrm{V}_{\mathrm{C}}>\mathrm{V}_{\mathrm{B}}$
- B$\mathrm{V}_{\mathrm{B}}>\mathrm{V}_{\mathrm{C}}$
- C$\mathrm{V}_{\mathrm{A}}>\mathrm{V}_{\mathrm{B}}$
- Correct answerD$\mathrm{V}_{\mathrm{A}}^{\mathrm{B}}=\mathrm{V}_{\mathrm{C}}$
Solution
Conducting surface behaves as equipotential surface.
Hence, the correct answer is option: 'D'.
