Solve the all parts of following question given below:
Question: You measure an electric field of 1.25*10^6N/C at a distance of 0.142m from a point charge. There is no other source of electric field in the region other than this point charge.
Part A: What is the electric flux through the surface of a sphere that has this charge at its center and that has radius 0.142m?
Part B: What is the magnitude of the charge?
