Question

Princess anna carries two mylar balloons that rub against the side of a circus tent, causing the balloons to separate. each balloon acquires 2.0 x 10-7c of charge. how large is the electric force between them when they are separated by a distance of 0.50 m?

Answer 1

The electric force between two charged objects is given by Coulomb's Law:

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

Where k is the Coulomb constant, q1 and q2 are the charges on the objects, and r is the distance between the objects.

Plugging in the values given in the problem, we have:

F = 8.99 x 10^9 N * m^2 / C^2 * (2.0 x 10^-7 C * 2.0 x 10^-7 C) / (0.50 m)^2

This simplifies to:

F = 2.80 x 10^-5 N

So the electric force between the two balloons is 2.80 x 10^-5 N.
