Question:

What is the magnitude of a point charge that would create an electric field of 4.80 N/C at points 2.90 m away?

Electric Field Due to a Point Charge

Electric field at a point is the Coulombic force experienced by a unit positive charge placed at that point. It is a vector quantity and obeys superposition principle for multiple point charges. The electric field due to a point charge depends on its position with respect to the point charge.

The electric field due to a point charge is given by,

{eq}\displaystyle{ E=\frac{kq}{r^2} } {/eq}

Where,

  • {eq}k=8.99\times10^9\ Nm^2/C^2 {/eq}...
