1)
The pendulum, in a wall clock, is a 'seconds pendulum', i.e., has a time period of 2s. The 'effective length' of a simple pendulum, that has the same time period, is nearly :
50 cm
200 cm
150 cm
100 cm
2)
A student measures the time period (T) of a simple pendulum for different values of its length (L). The student would get a straight line by plotting a graph between :
'L' and 'T' values
L and √T values
'√L' and 'T' values
√L and √T values
3)
Two pendulums of the same length are set up. If one bob is heavier than the other, what is the period of oscillation of the pendulum of the heavier bob?
Lesser than the lighter bob.
Greater than the lighter bob.
Remains the same.
Greater and same as the lighter bob.
4)
For a simple pendulum, the graph between l and T will be?
Curve
Hyperbola
Straight line
Parabola
5)
The opposition to free vibrations of bob of a simple pendulum due to presence of air around is called?
Damping
Frequency
Wavelength
Amplitude
6)
The number of oscillations completed by simple pendulum in one second is called?
Time period
Frequency
Amplitude
Wavelength
7)
What is the maximum displacement of the bob from its mean position to its extreme position called?
Time period
Wave length
Amplitude
Frequency
8)
If both the mass m of a simple pendulum and its length L are doubled, the period will
increase by a factor of 2.
increase by a factor of 0.71.
increase by a factor of 1.4
be unchanged.
9)
When the length of a simple pendulum is decreased by 600 mm, the period of oscillation is halved. What was the original length of the pendulum?
1000 mm
800 mm
1200 mm
1400 mm
10)
The time period of a pendulum on Earth is 1.0 s. What would be the period of a pendulum of the same length on a planet with half the density but twice the radius of Earth?
2.0 s
1.4 s
0.5 s
1.0 s
