the charge density in an insulateed solid sphere of radius find the electric field at a distance of from the center of the solid

Assuming the charged density in the insulated solid sphere of radius 3.1m is 8.8e-9, the electric field at 5.2 meters is 73.1256 .

Explanation:

The electric charge linear density is equal to 8.8 x

the radius of the sphere is 3.1m

The magnitude of the electric field at the radius of the sphere equal to 5.2 meters can be calculated with the formula ;

- E = λ / 4πε₀ [ r  / α ( α + r ) ]

Solution:

E =  8.8 x / 4πε₀ [ 3.1/ 5.2( 5.2 + 3.1) ]

= 1018.0995 [0.07183]

=  73.1256
