Answer 2

Calculating the Force Between Two Charged Spheres

To calculate the force between two charged spheres, we can use Coulomb's law, which states that the force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between their centers.

The formula for the force between two charged spheres is given by:

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

Where: - F is the force between the spheres - k is the Coulomb's constant (approximately 8.9875 x 10^9 N m^2/C^2) - q1 and q2 are the magnitudes of the charges on the spheres - r is the distance between the centers of the spheres

Calculating the Force

Given: - Charges of the spheres: 20 and 60 - Distance between the spheres: 0.3 m

Using the formula, we can calculate the force between the spheres:

F = (8.9875 x 10^9) * (|20 * 60|) / (0.3)^2

F ≈ 8.9875 x 10^9 * 1200 / 0.09

F ≈ 8.9875 x 10^9 * 13333.33

F ≈ 1.198 x 10^14 N

So, the force between the spheres is approximately 1.198 x 10^14 N.
