a. In the direction of the electric field.
b. Opposite the direction of the electric field.
c. Perpendicular to the electric field.
(B). Which one of the following statements is FALSE? Select one:
a. Electric field lines may cross each other.
b. Electric field lines must originate on a positive charge.
c. The line tangential to the field line gives the direction of the electric field at that point in space.
d. Electric field lines must terminate on a negative charge.
e. If the field lines are spaced closely together, it indicates a large magnitude of electric field.
(C). A solid metal sphere in electrostatic equilibrium has a positive net charge. How is the net charge distributed in the metal sphere? Select one:

b. Densely packed towards the center of the sphere.
c. Evenly distributed on the surface of the sphere.
