Question

Two charges of magnitude -2 q and + q aur located at point a, 0 and 4A, 0 Willy flux due to charge through a sphere of radius 3A with its Centre origin

Answer 1

Given:

The two charges of magnitudes -2q, +q

Radius be 3A

The points be (a,0) and (4A,0)

To find:

The flux due to charge through sphere

Solution:

The formula of flux is

∅=Q/ε₀

Here the Q= -2q

Put back in the formula

∅=-2q/ε₀

So the flux due to charge at center is -2q/ε₀
