Question

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

Answer 1

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
`i`.

Step-by-step explanation:

The electric charge linear density is equal to 8.8 x
`10^(-9)`

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 ) ]
`i`

Solution:

E = 8.8 x
`10^(-9)` / 4πε₀ [ 3.1/ 5.2( 5.2 + 3.1) ]
`i`

= 1018.0995 [0.07183]
`i`

= 73.1256
`i`
