Q. What is the relationship between the stopping potential and the maximum kinetic energy of emitted electrons in the photoelectric effect?
A.
Stopping potential is directly proportional to the work function
B.
Stopping potential is directly proportional to the maximum kinetic energy
C.
Stopping potential is inversely proportional to the frequency
D.
Stopping potential has no relation to kinetic energy
Solution
The stopping potential (V) is directly proportional to the maximum kinetic energy (KE) of the emitted electrons, given by the equation KE = eV, where e is the charge of the electron.
Correct Answer:
B
— Stopping potential is directly proportional to the maximum kinetic energy
Q. What is the relationship between the stopping potential and the maximum kinetic energy of the emitted electrons in the photoelectric effect?
A.
Stopping potential is directly proportional to the work function
B.
Stopping potential is inversely proportional to the maximum kinetic energy
C.
Stopping potential is equal to the maximum kinetic energy
D.
Stopping potential has no relation to the photoelectric effect
Solution
The stopping potential (V) is related to the maximum kinetic energy (KE) of the emitted electrons by the equation KE = eV, where e is the charge of the electron.
Correct Answer:
C
— Stopping potential is equal to the maximum kinetic energy
Q. What is the relationship between the wavelength and frequency of a wave?
A.
Wavelength is directly proportional to frequency
B.
Wavelength is inversely proportional to frequency
C.
Wavelength is equal to frequency
D.
Wavelength and frequency are unrelated
Solution
The relationship is given by the equation v = fλ, where v is the wave speed, f is the frequency, and λ is the wavelength. Thus, wavelength is inversely proportional to frequency.
Correct Answer:
B
— Wavelength is inversely proportional to frequency
Q. What is the relationship between voltage, current, and resistance according to Ohm's Law?
A.
V = I * R
B.
V = I / R
C.
V = R / I
D.
V = I + R
Solution
Ohm's Law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, with resistance (R) as the proportionality constant: V = I * R.
