0.20 The percentage errors in the measurement of mass andspeed are 2% and 3% respectively. How much will be themaximum error in the estimation of the kinetic energyobtained by measuring mass and speed?(a) 11%(c) 5%(b)(d)8%1%

Answer»

FORMULA

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%
