Question

Two negative charges are 10^−14 m away from each other. Using Coulomb's Law, which of the following is the electrical force between these two particles?

Option 1: 1.6×10^−19 N
Option 2: 8.99×10^9 N
Option 3: 1.6×10^−3 N
Option 4: 10^-14 N

Answer 1

The electrical force between two negative charges can be calculated using Coulomb's Law. Substituting the given values into the formula, we find that the electrical force is -8.99 x 10^-5 N.

Step-by-step explanation:

Coulomb's Law states that the electrical force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. The formula for calculating the electrical force is:

F = k * (q1 * q2) / r^2

Where F is the electrical force, k is the electrostatic constant (8.99 x 10^9), q1 and q2 are the charges of the particles, and r is the distance between the particles.

In this case, the charges of the particles are negative, so their product will be positive. The distance between the particles is given as 10^-14 m.

Substituting the values into the formula, we get:

F = (8.99 x 10^9) * (-10^-14)^2 = -8.99 x 10^-5 N

Therefore, the electrical force between the two negative charges is -8.99 x 10^-5 N.
