<strong>Physics</strong> <strong>212</strong> <strong>Exam</strong> I <strong>Sample</strong> <strong>Question</strong> <strong>Bank</strong> <strong>2008</strong>___ . In a static situation, if there is excess charge on a conductor then(A) the charge lies only on the surface of the conductor.(B) the charge is in constant motion throughout the conductor.(C) the charge evaporates from the conductor until there is no more excess charge.(D) the charge lies at the geometric center of the conductor.(E) the conductor explodes violently.___ . Identify the most correct statement(A) Gauss’s law is equivalent to Coulomb’s law.(B) Coulomb’s law is equivalent to Gauss’s law.(C) Gauss’s law is equivalent to Coulomb’s law only in situations with symmetry.(D) both (A) and (B).(E) Gauss’s law and Coulomb’s law are completely unrelated.___ . The electric field has magnitude 1000 N/C between parallel conducting plates separated by 5 mm (.005m).The potential difference between the plates is(A) 5V(B) 200V.(C) 5,000V.(D) 200,000V.(E) none of the above.___. The electric field is directed(A) away from areas with low electrical potential towards areas with higher electrical potential.(B) away from areas with high electrical potential towards areas with lower electrical potential.(C) along paths of constant electric potential.(D) along spirals.(E) electric fields are scalar quantities, and thus have no direction associated with them.___. The electric field magnitude near (but outside of) an irregularly shaped conductor(A) will be greatest where the surface has the sharpest curvature.(B) will be greatest where the surface has the flattest curvature.(C) does not depend upon the shape of the conductor.(D) will necessarily be zero.(E) trick question; since the electric field is a scalar quantity, the term “electric field magnitude” ismeaningless.___ . The electric potential is(A) is potential energy per unit charge.(B) is electrical force per unit charge.(C) is simply electrical energy.(D) is simply electrical charge.(E) always zero within conductors.
