Question

In a thundercloud there may be an electric charge of 24 C near the top of the cloud and −24 C near the bottom of the cloud. If these charges are separated by about 2 km, what is the magnitude of the electric force between these two sets of charges? The value of the electric force constant is 8.98755 × 109 N · m2 /C 2 .

Answer 1

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.
