1. Heisenberg
2. Bohr
3. Teller
4. Pauli

The force acting between two point charges can be computed using which of the following laws?

2. Ampere’s Law
3. Coulomb’s Law
4. Newton’s Second Law.

For an infinite sheet of positive charge, the electric field lines:

1.  run parallel to the sheet of charge
2.  are perpendicular to the sheet of charge and point in toward the sheet
3.  are perpendicular to the sheet of charge and point away from the sheet
4.  fall off as one over r squared

Five coulombs of charge are placed on a thin-walled conducting shell. Once the charge has come to rest, the electric potential inside the hollow conducting shell is found to be:

1. zero
2. uniform inside the sphere and equal to the electric potential on the surface of the sphere
3. smaller than the electric potential outside the sphere
4. varying as one over r squared.
