. Time period of a simple pendulum depends on
A: Mass of bob
B: Length of string
C: Dimension of bob
D: Material of the bob
Time period of simple pendulum
Here, l is the length of the pendulum string and g is the acceleration due to gravity which is constant.
Therefore, the time period of a simple pendulum depends on the length of the string.
Hence, Option (B) is correct. ( Length of string )
