Question

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

Answer 1

Answer:

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.
