Question

A raindrop charged to 10 μC experiences electric field of 10,000 V/m from a tip of a tree branch. What is the electric force acting on the raindrop? (1μC= 10^-6C)

a. 0.001 N
b. 100 N
c. 0.1N
d. 0.9 N

Answer 1

(C). The magnitude of electric force acting on the raindrop is 0.1 N.

Step-by-step explanation:

Given;

charge of the raindrop, Q = 10 μC = 10 x 10⁻⁶ C

electric field strength, E = 10,000 V/m

The electric force acting on the raindrop is given as;

F = EQ

where;

F is the electric force

Substitute the given values and solve for F.

F = (10,000)(10 x 10⁻⁶)

F = 0.1 N

Therefore, the magnitude of electric force acting on the raindrop is 0.1 N.
