Expert Solution
Step 1: Electric field due to point charge

The electric field at a point at a distance r due to a point charge q is given by,

E with rightwards arrow on top equals k q over r squared r with hat on top

Where:

k equals 8.99 cross times 10 to the power of 9 space text Nm end text squared divided by text C end text squared, is Coulomb's constant.

 r with hat on top is the unit vector along the line joining the point charge and the position where the electric field needs to be found.
