Question

A circle of radius R is drawn in a uniform electric field E as shown in the figure $ {{V}_{A}}, $ $ {{V}_{B}},{{V}_{C}} $ and $ {{V}_{D}} $ are respectively the potentials of points A, B, C and D at the periphery of the circle

• A. $ {{V}_{A}}={{V}_{C}};{{V}_{B}}={{V}_{D}} $
• B. $ {{V}_{A}}={{V}_{C}};{{V}_{B}}<{{V}_{D}} $
• C. $ {{V}_{A}}>{{V}_{C}};{{V}_{B}}={{V}_{D}} $
• D. $ {{V}_{A}}<{{V}_{C}};{{V}_{B}}={{V}_{D}} $

Answer 1

Answer: (B)

: Potential will be minimum at B Potential will be maximum at D Potential at A = potential at C $ \therefore $ $ {{V}_{A}}={{V}_{C}},{{V}_{B}}<{{V}_{D}} $
