Question

An infinitely large plane carries a uniformly distributed charge such that the charge per unit area is 3.47E-6 C/m2. What is the electric field magnitude |E| at a point that is 2.40 m from the plane

Answer 1

Answer:$1.95\times 10^5\ N/C$

Explanation:

Given

The charge per unit area on the plate is $\sigma =3.47\times 10^{-6}\ C/m^2$

Electric for a infinitely large plane is given by

$E=\dfrac{\sigma }{2\epsilon_o}$

Therefore, electric field at a point 2.4 m from the plane is

$\Rightarrow E=\dfrac{3.47\times 10^{-6}}{2\times 8.854\times 10^{-12}}\\\\\Rightarrow E=0.195\times 10^6\ N/C$
