Academics

Two tiny conducting spheres are identical and carry charges of-20.0 µC and +50.0 µC. They are separated by a distance of2.10 cm.

(a) What is the magnitude of the force that each sphere experiences, and is the force attractive or repulsive?

(b) The spheres are brought into contact and then separated to adistance of 2.10 cm. Determine themagnitude of the force that each sphere now experiences, and statewhether the force is attractive or repulsive.
