Electrostatics Question 356
Question: The electric field near a conducting surface having a uniform surface charge density $ \sigma $ is given by [MP PMT 1994]
Options:
A) $ \frac{\sigma }{{\varepsilon _{0}}} $ and is parallel to the surface
B) $ \frac{2\sigma }{{\varepsilon _{0}}} $ and is parallel to the surface
C) $ \frac{\sigma }{{\varepsilon _{0}}} $ and is normal to the surface
D) $ \frac{2\sigma }{{\varepsilon _{0}}} $ and is normal to the surface
Show Answer
Answer:
Correct Answer: C
Solution:
Electric field near the conductor surface is given by $ \frac{\sigma }{{\varepsilon _{0}}} $ and it is perpendicular to surface.
