You measure an electric field of 125times106nc at a

Question

Solve the all parts of following problem:

Problem: You measure an electric field of 1.25×10⁶N/C at a distance of 0.158m from a point charge. There is no other source of electric field in the region other than this point charge.

Part I: What is the electric flux through the surface of a sphere that has this charge at its center and that has radius 0.158m?

Part II: What is the magnitude of the charge?

I need help to find the electric flux through the surface of a sphere.
