Question

Electric lines of force are as shown in the figure. Then potential at point $P$

• A. is zero
• B. is not zero
• C. may be zero
• D. is not defined

Answer 1

Answer: (C)

Electric field lines are perpendicular to metal body or conductor. The given structure shows a conducting body. Electric lines of force do not enter a conductor. Potential of a conductor is constant but not necessarily zero.
