Question

A hollow sphere of radius 1.66 m is in a region where the electric field is radial and directed toward the center of the sphere. If the magnitude of the field at the surface of the sphere is 21.5 N/C, what is the net electric flux through the spherical surface?

Answer 1

Answer:

The value of flux will be "744.1 N.m²/C".

Explanation:

The given values are:

Magnitude,

E = 21.5 N/C

Radius,

R = 1.66 m

As we know,

⇒  $Flux = Area\times E$

On putting the estimated values, we get

⇒           $=-21.5\tines (4\times \pi\times 1.66^2 )$

⇒           $=744.1 \ N.m^2/C$
