We have an initially uncharged hollow metallic sphere with radius of 5.0 cm.I place a small object with a charge of +10 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.(k_e = 8.99 x 10⁹ N*m²/C²)

The electric field at a point outside a charged sphere is given by E = k_e * Q / r^2. Here, Q = 10 µC = 10 x 10^-6 C, r = 0.1 m, and k_e = 8.99 x 10^9 N m^2/C^2. Plugging in these values gives E = 8.99 x 10^9 * 10 x 10^-6 / (0.1)^2 = 8.99 x 10^6 N/C, which is approximately 9.0 x 10^6 N/C.
