1. We wish to determine the electric field at a point near a positively charged metal sphere (a good conductor).We do so by bringing a small positive test charge q0, to this point and measure the force F0 on it. F0/q0 will be ____________ the electric field E̅ as it was at that point before the test charge was present.
(a) Greater than
(b) Less than
(c) Equal to
2. We are usually not aware of the electric force acting between two everyday objects because
(a) The electric force is one of the weakest forces in nature.
(b) The electric force is due to microscopic-sized particles such as electrons and protons.
(c) The electric force is invisible.
(d) Most everyday objects have as many plus charges as minus charges.
