A Thin Spherical Metal Shell of Radius $8.0 \mathrm {~cm}$ Carries $7.5 \mu \mathrm { C }$

question 60

Short Answer

A thin spherical metal shell of radius $8.0 \mathrm {~cm}$ carries $7.5 \mu \mathrm { C }$ of excess charge. What is the magnitude of the electric field it produces at the following places? $\left( k = 1 / 4 \pi \varepsilon _ { 0 } = 9.0 \times 10 ^ { 9 } \right.$ $\mathrm { N } \cdot \mathrm { m } ^ { 2 } / \mathrm { C } ^ { 2 }$ )
(a) at $1.0 \mathrm {~cm}$ above the surface
(b) at $7.0 \mathrm {~cm}$ from the center of the sphere
