Question

Factors on which time period depends? (2)
explain them briefly.

Answer 1

→Question: Factors on which time period depends?

→Answer:

⇔Let's know what is time period?

↔The time taken to complete one oscillation by a simple pendulum. It's unit is second (s).

⇔Factor's on which time period depends:

• Effective length : The time period varies directly with the square root of length of the pendulum. T ∝ √I.
• Acceleration due to gravity : The time period varies inversely with the square root of the acceleration due to gravity. T ∝ √1÷g.

⇔Extra Information:

⇒Expression for the time period of the simple pendulum:

• T = 2π √1/l   or T² = 4π² l/g

⇔Where:

• T = time period
• g = acceleration due to gravity
• l = effective length of the pendulum.

Answer 2

Effective length : The time period varies directly with the square root of length of the pendulum. T ∝ √I.

Acceleration due to gravity : The time period varies inversely with the square root of the acceleration due to gravity. T ∝ √1÷g.
