The force on a unit positive charge at the given position is determined as 1.8 x 10⁻⁸ N.

Force on the charge

The force on the charge is calculated as follows;

F = k(q1q2)/r²

where;

  • r is the distance between the charges = 2 m - 1m = 1m

F = (9 x 10⁹ x 10⁻⁹ x 2 x 10⁻⁹)/(1)²

F = 1.8 x 10⁻⁸ N

Thus, the force on a unit positive charge at the given position is determined as 1.8 x 10⁻⁸ N.
