A point charge of 1.8μC is at the centre of cubical Gaussian surface 55cm on edge. What is the net electric flux through the surface?

View answer and explanation

Correct option: C

2.0 \times {10^5}\mathrm{N} - {\mathrm{m}^2}{\mathrm{C}^{ - 1}}

Option C (

2.0 \times {10^5}\mathrm{N} - {\mathrm{m}^2}{\mathrm{C}^{ - 1}}

) is correct because it is the net electric flux calculated using Gauss's law.

Assertion:- Electric field lines do not cut at any point.
Reason:- At any point, there is only one direction of electric field. Statement-I: A positive point charge is brought in an electric field, the electric field at neary by point will increase

Statement-II: Electric field produced by charge may favour the existing electric filed Two particles having equal mass and charge
are separated by a distance
