We have an initially uncharged hollow metallic sphere with radius of 5.0 cm.I place a small object with a charge of +20 µC at the center of the sphere through a hole in the surface.Find the electric field present at a point 10 cm from the sphere's center.(ke = 8.99 × 109 N⋅m2/C2)
A) 3.6E+7 N/C
B) 9.0E+6 N/C
C) 1.8E+7 N/C
D) 4.5E+6 N/C
E) 2.7E+7 N/C
