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* 10^5\ N/C`

Step-by-step explanation:

Given

The charge per unit area on the plate is
`\sigma =3.47* 10^(-6)\ C/m^2`

Electric for a infinitely large plane is given by

`E=(\sigma )/(2\epsilon_o)`

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

`\Rightarrow E=(3.47* 10^(-6))/(2* 8.854* 10^(-12))\\\\\Rightarrow E=0.195* 10^6\ N/C`
