Move on to electric force. Blow up the two balloons and knot them. Then tie a thread onto each balloon.
Suspend the two balloons using tape so that they're about six inches apart, and check that they don't
move or interact. Rub both balloons with wool or fur. If wool or fur is not available, rub the balloons on
your hair. Do they attract or repel (push away) each other?

The nuclear potential that binds protons and neutrons in the nucleus of an atom is often approximated by a square well. imagine a proton conned in an innite square well of length 105 nm, a typical nuclear diameter. calculate the wavelength and energy associated with the photon that is emitted when the proton undergoes a transition from the rst excited state (n 2) to the ground state (n 1). in what region of the electromagnetic spectrum does this wavelength belong?
