3. Two identically shaped spheres are charged so that 1 sphere has a charge of + 4.00 C and the other has a charge of -1.00 C. If the two spheres are allowed to touch and then are moved to a distance of 0.200 m, what is the magnitude of the electric force between them?

Homework Answers

Answer #1

When the spheres are allowed to touch, charges flow from one sphere to another until the charges on them are equal.
The charge on each sphere is
Q = 4.00 C + (- 1.00 C ) / 2 = 1.50 C.
The force between the spheres when they are separated by a distance of 0.200 m is
F = k Q2 / r2
Where r =0.200 m, the distance between the charges.
F = 9 x 109 x (1.50 x 10-6 C)2 / 0.2002
F =  0.506 N

Two small spheres, A and B, are separated by a distance of 1.5 m as shown below. Sphere A has a charge of 3 μC and Sphere B has a charge of -6 μC. (The prefix \"μ\" means \"micro\" which is a \"millionth.\" So, 1 microCoulomb = one-millionth of a Coulomb = 10-6 C.) Sphere C, is now moved to a new position that is directly above Sphere A. The distance between A and C is still half the distance...

You have two identical metal spheres, one with a -2.0-µC charge and one with a 20.0-µC charge, located 5 cm apart. They are brought into contact with each other, which distributes the charge evenly over the available surface area, and then moved back to their original positions. Determine the ratio of the magnitude of the new electric force between them to the original electric force between them.
