Question 1
A 1.0-μF capacitor is charged until it acquires a potential difference of

across its plates, and then the emf source is removed. If the capacitor is then discharged through a

resistance, what is the voltage drop across the capacitor

after beginning the discharge?
◦ -16 V
◦ 920 V
◦ 880 V
◦ 16 V
Question 2
A positive charge is moving to the right and experiences an upward magnetic force, as shown in the figure. In which direction must the magnetic field have a component?

◦ into the page
◦ out of the page
◦ to the left
◦ upward
◦ to the right
