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)

Define the terms: (i) oscillation (ii) amplitude (iii) frequency, and (iv) time period as related to a simple pendulum

Name two factors on which the time period of a simple pendulum does not depend.
