To estimate (g ) from (g=4 ^2 L T^2 ), error in measurement of (L ) is ( 2 % ) and error in measurement of (T ) is ( 3 % ). The error in estimated (g ) will be
Options
- A( 8 % )
- B( 5 % )
- C( 3 % )
- D( 6 % )
Correct answer
A. ( 8 % )
Step-by-step solution
( g=4 ^2 L T^2 ) Percentage error in the estimation of (g ) is given as, ( aligned g g 100 & = ( L L 100+2 T T 100 ) & = (2 %+2 3 %) & = (2 %+6 %)= 8 % aligned )
