Question

If the length and time period of an oscillating pendulum have errors of 1 percent and 3 percent respectively then the error in measurement of acceleration due to gravity is
​

Answer 1

Answer:

Now, |ΔL/L| = 0.01 and |ΔT/T|=0.03. So, |Δg/g| = 0.07. Hence, the relative error in the measurement of gravity is 7%
