A solid metal sphere with radius 0.450 m carries a net charge of 0.250 nC. Find the magnitude of the electric field (a) at a point 0.100 m outside the surface of the sphere and (b) at a point inside the sphere, 0.100 m below the surface.

Solution 14E Step 1 : Introduction : In this question, we need to find the magnitude of electric field at point 0.100 m on the surface of the sphere In the second part, we need to find the point inside the sphere at 0.100 m below the surface Data given Radius r = 0.450 m Charge Q = 0.250 × 10 C 9
