Question

Time period T of a simple pendulum of length l is given by T equal to 2pi into root over l/g<br /> if the length is increased by 2% then an approximate change in the time period is​

Answer 1

Answer:

Step-by-step explanation:

T = 2π√(L/g)

From above

ΔT/T × 100 = 0.5 × (ΔL/L × 100)

= 0.5 × 2%

= 1%
