Question

The maximum percentage error in the measurement of
length / and acceleration due to gravity g are 2% and
4% respectively. The maximum percentage error in the
calculation of time period of a simple pendulum is
3%
2%
6%
5%​

Answer 1

Answer:

X=a+b

Δa= absolute error in a

Δb= absolute error in b

Δx= absolute error in x

maximum error possible

Δx=±(Δa+Δb)

% error on the value of x=(

a+b

Δa+Δb

)×100%

=(
