023 (part 1 of 2) 10.0 points

Two conducting spheres have identical radii.

Initially they have charges of opposite sign

and unequal magnitudes with the magnitude

of the positive charge larger than the magnitude of the negative charge. They attract

each other with a force of 0.237 N when separated by 0.5 m.

The spheres are suddenly connected by a thin

conducting wire, which is then removed.

Connected + +

Now the spheres repel each other with a force

of 0.024 N.

Final + +

What is the magnitude of the positive

charge?

Answer in units of C

What is the negative charge?

Answer in units of C

Explanation / Answer

F(initial) = 0.237N, r = 0.5 m

F(initial) = k(q-)(q+)/r
