Question

Percentage error inMeasurement of mass speed are 2% and 3% respectively. The error in kinetic energy obtained by measuring mass and speed, will be

Answer 1

1/2 m(v)^2

So for finding error in multiplication TOTAL %UNCERTANITY ARE ADDED UP aand power is multiplied by percentage uncertainty

Uncertanity = error

Error in mass 2% and in velocity 3%

So error in velocity should be 2(3%)= 6%

Total error =2%+6%=8%

HOPE THIS HELPED U GUYS!
