a thundercloud whose base is 500m above the ground. The potential difference between the base of the cloud and the m ground is 200MV. A raindrop with a charge of 4.0 x 10-12C is in the region between the cloud and the ground. What is the electrical force on the raindrop? A 1.6 x 10-6N B 8.0 x 10-4N C 1.6 x 10-3N D 0.40N

1.6*10⁻⁶ N.

Explanation:

From the question,

F = (V/r) q ... Equation 1

Where F = Electric force on the raindrop, V = Potential difference between the base of the cloud and the ground, r = distance between the base of the cloud and the ground, q = the charge on a rain drop.

Given: V = 200MV = 200*10⁶ V, r = 500 m, q = 4.0*10⁻¹² C.

Substitute these values into equation 1

F = [ (200*10⁶) / 500]*4.0*10⁻¹²

F = 1.6*10⁻⁶ N.
