Q. If a current-carrying wire is bent into a circular loop, what is the direction of the magnetic field at the center of the loop according to the Biot-Savart Law?
A.
Out of the plane of the loop
B.
Into the plane of the loop
C.
Clockwise
D.
Counterclockwise
Solution
According to the right-hand rule applied to the Biot-Savart Law, the magnetic field at the center of a circular loop of current is directed out of the plane of the loop.
Q. If a damped oscillator has a mass of 5 kg, a spring constant of 20 N/m, and a damping coefficient of 1 kg/s, what is the natural frequency of the system?
A.
1 Hz
B.
2 Hz
C.
3 Hz
D.
4 Hz
Solution
Natural frequency (ω_n) = √(k/m) = √(20/5) = √4 = 2 Hz.
