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.

The correct answer is false.
Answer:
Zero
Explanation:
It is given that the charge is uniformly spread at the surface of hollow spherical shells.
There is no charge with in the hollo shell. hence, with zero charge the electric field intensity is also zero.
Thus,
Magnitude of the electric field strength inside the hollow shell at r is zero
