What magnitude charge creates a 1.0 n/c electric field at a point 1.0 m away?

Explanation:

The electric field produced by a single point charge is given by:

where

k is the Coulomb's constant

q is the charge

r is the distance from the charge

In this problem, we have

E = 1.0 N/C (magnitude of the electric field)

r = 1.0 m (distance from the charge)

Solving the equation for q, we find the charge:
