Final answer:
The period of the pendulum is approximately 0.128 seconds.
Step-by-step explanation:
The period of a pendulum can be calculated using the formula:
T = 2π × √(L / g)
where T is the period, π is a mathematical constant approximately equal to 3.14159, L is the length of the string, and g is the acceleration due to gravity.
In this case, the length of the string is 2 cm, which is 0.02 meters. The acceleration due to gravity can be approximated as 9.8 m/s2. Plugging these values into the formula, we get:
T = 2π × √(0.02 / 9.8)
Simplifying, we find that the period of the pendulum is approximately 0.128 seconds.
