Electrostatics Question 666
Question: A uniform electric field pointing in positive $ x $ -direction exists in a region. Let $ A $ be the origin, $ B $ be the point on the $ x $ -axis at $ x=+1 $ cm and $ C $ be the point on the $ y $ -axis at $ y=+1 $ cm. Then the potentials at the points $ A $ , $ B $ and $ C $ satisfy
Options:
A) $ V _{A}<V _{B} $
B) $ V _{A}>V _{B} $
C) $ V _{A}<V _{C} $
D) $ V _{A}>V _{C} $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] Potential decreases in the direction of electric field. Dotted lines are equipotential lines $ \therefore {V _{ _{A}}}=V _{C} $ and $ V _{A}>V _{B} $
