Length of the pipe = 0.39 m
Third harmonic frequency = 1400 Hz
For the third harmonic:
Wavelength =
The center of the open pipe will host a node and the nearest anti - node from the center will be at the 0.25 × wavelength
Distance from center = 0.25 × wavelength
Distance =
Plugging the value of the length of the pipe (L) = 0.39 m = 39 cm
Distance =
Distance from the center to the nearest anti - node = 6.5 cm
Hence, the nearest distance to the anti - node from the center = 6.5 cm
So, option C is correct.
Answer:
114.92749 keV
Explanation:
r = Radius of trajectory
m = Mass of electron =
B = Magnetic field = 0.044 T
q = Charge of electron =
The centripetal force and the magnetic forces are conserved
Velocity of first electron
Velocity of second electron
Total kinetic energy is given by
Converting to eV
The energy of incident electron is 114.92749 keV
