An election has an initial velocity to the south but is observed to curve upward

Question

An election has an initial velocity to the south but is observed to curve upward as the result of a magnetic field. This magnetic field must have a component to the west. to the east. upward. downward. To the north. A 120-V rms voltage is applied across a 6.00-mu F capacitor and a 100-Ohm resistor. If the frequency of the generator is 60.0 Hz. what is the impedance of this circuit? 150 Ohm 453 Ohm 353 Ohm 253 Ohm 553 Ohm A 120-V rms voltage at 1.00 kHz is applied to a resistor and an inductor in series. If the total impedance of this circuit is 110 Ohm, what is the maximum (peak) value of the current? 0.49 A 1.09 A 1.84 A 104 A 1.54 A For the circuit shown in the figure, V= 60 V, C = 40 mu F, R = 0.90 M Ohm, and the battery is ideal. Initially the switch S is open and the capacitor is uncharged. The switch is then closed at time t = 0.00 s. At a given instant after closing the switch, the potential difference across the capacitor is twice the potential difference across the resistor. At that instant, what is the charge on the capacitor? 1600 mu C 1400 mu C 1200 mu C 890 mu C 600 mu.C

Explanation / Answer

7) C- upward (since the electron will travel in the direction of magnetic field)
