Q1
Easy
What is the maximum displacement from the mean position in Simple Harmonic Motion (SHM) called?
A.
Amplitude
B.
Frequency
C.
Period
D.
Wavelength
Show Answer & Explanation
Correct Answer: A
The maximum displacement from the mean position in SHM is called amplitude. It represents the highest point the oscillating object reaches relative to its equilibrium position.
Q2
Easy
A mass-spring system undergoes SHM with a period of 2 seconds. What is its frequency?
A.
0.5 Hz
B.
1 Hz
C.
2 Hz
D.
4 Hz
Show Answer & Explanation
Correct Answer: A
Frequency is the reciprocal of the period. Thus, frequency = 1/Period = 1/2 seconds = 0.5 Hz.
Q3
Easy
In SHM, if the amplitude is doubled, what happens to the total energy of the system?
A.
It remains the same
B.
It doubles
C.
It quadruples
D.
It halves
Show Answer & Explanation
Correct Answer: C
The total energy in SHM is proportional to the square of the amplitude. If the amplitude is doubled, the energy increases by a factor of four (2^2 = 4).
Q4
Medium
A simple harmonic oscillator has a time period of 4 seconds. What is its frequency?
A.
0.25 Hz
B.
0.5 Hz
C.
2.0 Hz
D.
4.0 Hz
Show Answer & Explanation
Correct Answer: A
Frequency is the reciprocal of time period. Thus, frequency = 1/T = 1/4 seconds = 0.25 Hz.
Q5
Medium
In a simple harmonic motion, the maximum velocity occurs at which position?
A.
Equilibrium position
B.
Maximum displacement
C.
Mean position
D.
None of the above
Show Answer & Explanation
Correct Answer: A
The maximum velocity in SHM occurs at the equilibrium position where the potential energy is minimum and kinetic energy is maximum.
Q6
Medium
A mass-spring system oscillates with an amplitude of 0.05 m. What is the maximum potential energy if the spring constant is 200 N/m?
A.
0.25 J
B.
0.5 J
C.
1 J
D.
2 J
Show Answer & Explanation
Correct Answer: A
Maximum potential energy in the spring is given by PE = (1/2)kx². Here, PE = (1/2) * 200 * (0.05)² = 0.25 J.
Q7
Medium
The displacement of a particle in SHM is given by x(t) = 0.1 cos(2πt). What is the frequency of the oscillation?
A.
0.5 Hz
B.
1 Hz
C.
2 Hz
D.
4 Hz
Show Answer & Explanation
Correct Answer: B
The standard form x(t) = A cos(ωt) gives frequency f = ω/(2π). Here, ω = 2π, thus f = 1 Hz.
Q8
Hard
A body performing simple harmonic motion has a maximum velocity of 10 m/s and a maximum displacement of 5 m. What is the frequency of its oscillation?
A.
0.5 Hz
B.
1 Hz
C.
2 Hz
D.
3 Hz
Show Answer & Explanation
Correct Answer: B
The maximum velocity (v_max) in SHM is given by v_max = Aω, where A is the amplitude and ω is the angular frequency. Thus, ω = v_max/A = 10 m/s / 5 m = 2 rad/s. The frequency (f) is ω/(2π) = 2/(2π) = 1 Hz.
Q9
Hard
A mass-spring system oscillates with an amplitude of 0.1 m and a spring constant of 200 N/m. What is the total energy of the system at maximum displacement?
A.
1 J
B.
2 J
C.
0.5 J
D.
0.1 J
Show Answer & Explanation
Correct Answer: A
The total mechanical energy in a mass-spring system is given by E = (1/2) k A². Substituting k = 200 N/m and A = 0.1 m gives E = (1/2) * 200 * (0.1)² = 1 J.
Q10
Hard
If the period of a simple harmonic oscillator is 4 seconds, what is the time taken to complete a quarter of an oscillation?
A.
1 s
B.
2 s
C.
3 s
D.
4 s
Show Answer & Explanation
Correct Answer: A
The time for one complete oscillation (T) is 4 seconds. A quarter of an oscillation takes T/4 = 4/4 = 1 second.
