Answer:

Electric force, $F=1.29\times 10^6\ N$

Explanation:

Given that,

Charge 1, $q_1=24\ C$

Charge 2, $q_2=-24\ C$

Distance between charges, d = 2 km

The electric force is given by :

$F=k\dfrac{q_1q_2}{d^2}$

k is the electrostatic constant

$F=8.98755\times 10^9\times \dfrac{(24)^2}{(2\times 10^3)^2}$

F = 1294207.2 N

or

$F=1.29\times 10^6\ N$

Hence, this is the required solution.
