A solid metal sphere with radius 0.410 carries a net charge of 0.290 Find the magnitude of the electric field at a point 0.116 outside the surface of the sphere.
Apply Gauss' law at a distance r = 0.526 m from the center of the sphere.
You should have provided units for the charge. Are they Coulombs or microcoulombs? You also did not provide units for the distances.
Unless you understand the importance of units in physics and enginering you should not be taking these courses. Find a different career.
