QUESTION:
You measure an electric field of 1.25 X 106 N/C at a distance of 0.150 m from a point charge. There is no other source of electric field in the region other than this point charge. (a) What is the electric flux through the surface of a sphere that has this charge at its center and that has radius 0.150 m? (b) What is the magnitude of this charge?
ANSWER:Solution 3E The expression for electric flux through a closed surface is given by = E.dA 6 Given, E = 1.25 × 10 N/C Radius of the sphere r = 0.150 m Area of the sphere A = 4 × (0.150) m = 0.283 m 2 (a) h
