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.
