Question

A Point charge of 2 micro coulomb is at the center of a cubic Gaussian surface 9cm on edge what is the net electric field the surface, calculate the flux through 1 Face of the cube​

Answer 1

Answer:

Explanation:

According to Gauss's theorem of static electricity the net flux through the closed surface( of any shape and size)is Q/eo. Here, Q is net charge enclosed by the surface and eo is electric permittivity of the space.

Here, charged enclosed by the given closed surface is

Q=2 microCoulomb=2x10^-6C.

eo=8.85x10^-12 F/m.

Therefore, net flux asked for is =(2x10^-6)C/(8.85x10^-12)F/m=2.26x10^-7 Cm/F or (N/C)m^2
