Question

in a thundercloud, there may be electric charges of 140.0 c near the top of the cloud and 240.0 c near the bottom of the cloud. these charges are separated by 2.00 km. what is the electric force on the top charge?

Answer 1

The electric force between the two charges is given by Coulomb's Law:

F = k * q1 * q2 / r^2

Where:

k = Coulomb constant = 8.99 x 10^9 N * m^2 / C^2

q1 = 140.0 C

q2 = 240.0 C

r = 2.00 km = 2.00 x 10^3 m

F = k * 140.0 * 240.0 / (2.00 x 10^3)^2

F = 1.7 x 10^9 N

So, the electric force on the top charge is 1.7 x 10^9 N.
