The error in the measurement of the length of a simple pendulum is 0.1% and the error in the time period is 2%. What is the possible percentage of error in the physical quantity having the dimensional formula `LT^(-2)`.

Text Solution

Verified by Experts

Percentage error in `LT^(-2)` is
` delta a = ((Delta L)/( L) + 2. (Delta T)/( T) ) xx 100 = ((0.1)/( 100) + (2(2))/( 100) ) xx 100 = 4.1%`
