Question

1. If q1 and q2 are opposite charges, they attract and the electric potential is a negative value, as in the case of gravitational potential energy. True or False? 2. The force vectors on a positively charged sphere are away from the sphere. True or False? 3. For a charge q1 moving in the electric field of q2 in a vacuum, the loss of electric potential energy is equal to the gain in kinetic energy. True or False? 4. Coulomb’s law is extremely accurate under the conditions that the spheres are small and that the spheres are also small compared to the distance between them. True or False? 5. A small negative charge is used to determine the direction of the electric field lines around a charge. True or False?

          1.
If q1 and q2 are
opposite charges, they attract and the electric potential is a
negative value, as in the case of gravitational potential
energy. True or False?
2. The force vectors on a positively charged sphere
are away from the sphere. True or False?
3. For a charge q1 moving in
the electric field of q2 in a
vacuum, the loss of electric potential energy is equal
to the gain in kinetic energy. True or False?
4. Coulomb’s law is extremely accurate under the conditions
that the spheres are small and that the spheres are also
small compared to the distance between them. True or
False?
5. A small negative charge is used to
determine the direction of the electric field lines around a
charge. True or False?
