A)
toward the curve's center
B)
away from the curve's center
C)

D)
toward the back of the car
E)
the net force is zero
Question 2
When a charged capacitor is connected to an inductor, the value of the charge on the capacitor oscillates and so does the current in the circuit.
What changes in the current would take place if the same capacitor, with the same initial charge, is connected to a inductor with a larger inductance? A)
Both the period of oscillation of the current and its maximum value would increase.
B)
The period of oscillation of the current would stay the same but its maximum value would increase.
C)
The period of oscillation of the current would decrease but its maximum value would remain the same.
D)
The period of oscillation of the current would increase but its maximum value would remain the same.
E)
Both the period of oscillation of the current and its maximum value would decrease.
