[Ryo124]

Homework Statement

You have an electrically charged sphere.

The strength of an electric field 0.1 m away from the center of the sphere is 30,000 N/C.

The radius of the sphere is 0.05 m.

What is the electric charge (Q) of the sphere?

Homework Equations

E = F/q - E = -V/d

The Attempt at a Solution
