The length of pendalum is measured as 1....

The length of pendalum is measured as `1.01m` and time for 30 oscillations is measured as one minuted 3 secounds. Error in length is `0.01m` minute `3` seconds. The percenrage error in the measurement of acceleration due to gravity is.

A

`1`

B

`5`

C

`10`

D

`15`

Text Solution

Verified by Experts

The correct Answer is:
C
`T = 2pi sqrt((l)/(g)), (Delta g)/(g) xx 100 = (Delta l)/(l) xx 100+2 (Delta T)/(T) xx 100`
