Question

A point charge q1 = 3.30nC is located on the x-axis at x= 1.90m , and a second point charge q2= -6.40 nC is on the y-axis at y= 1.15 m.

1-)What is the total electric flux due to these two point charges through a spherical surface centered at the origin and with radius r1= 0.625m ?

Answer 1

Explanation:

charge q1 is placed at x = 1.90 m and the charge q2 is placed at y = 1.15 m

here, the charge enclosed in a sphere is zero as the radius of sphere is 0.625 m which is less than the x = 1.90 m and y = 1.15 m. So by the Gauss's theorem,

`\phi =(q)/(\epsilon _(0))`

where q is the charge enclosed, as the charge enclosed is zero so the electric flux is zero.
