To find the magnitude of the point charge, we use the formula for the electric field due to a point charge:

$$E = \frac{kq}{r^2}$$

where

$$E$$ is the electric field,

$$k$$ is Coulomb's constant, approximately $$9 \times 10^9 \, \mathrm{N \, m^2/C^2}$$,

$$q$$ is the charge, and

$$r$$ is the distance f
