Question

A conductor $P Q$ as shown in figure is charged. $\sigma_{A}, \sigma_{B}, \sigma_{C}$ and $\sigma_{D}$ are surface charge densities of points $A, B, C$ and D resnectively

• A. $\sigma_{A}<\sigma_{B}<\sigma_{C}<\sigma_{D}$
• B. $\sigma_{A}=\sigma_{B}=\sigma_{C}>\sigma_{D}$
• C. $\sigma_{A}>\sigma_{C}>\sigma_{B}>\sigma_{D}$
• D. $\sigma_{A}=\sigma_{B}=\sigma_{C}=\sigma_{D}$

Answer 1

Answer: (C)

Sharp surfaces will have high charge density.
