Question

If percentage errors of measurement in
velocity and mass are 2% and 4%respectively. Find the percentage error

Answer 1

As-Salamu-Alykum


__________


Percentage error in Mass=2%


Percentage error in velocity =3%


Percentage error in kinetic energy = %error in m + ( % error in velocity)^2


Percentage error in kinettic energy = 2 + (3)^2


Percentage error in kinetic energy = 2 +9


Percentage error in kinetic energy =11%
