The time period of a simple pendulum depends on :

1. Length of pendulum
2. Amplitude of oscillation
3. Mass of bob
4. All of the above

The time period of two pendulums of length 1 m and 16 m are in ratio :

1. 1 : 16
2. 1 : 4
3. 16 : 1
4. 4 : 1

The length of a seconds' pendulum is nearly —

1. 0.5 m
2. 9.8 m
3. 1.0 m
4. 2.0 m

Identify the incorrect statement(s) from the following :

(I) The time period of oscillations depends on the extent of swing on either side.

(II) The time period of oscillations is directly proportional to the square root of acceleration due to gravity.

(III) The time period of oscillations is inversely proportional to the square root of its effective length.

(IV) The time period of oscillations does not depend on the mass or material of the suspended body.

1. (II) and (III)
2. Only (II)
3. Only (IV)
4. (I), (II) and (III)
