Question

A conductor $PQ$ 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.
