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.
