Question
The percentage errors in the measurement of mass and speed are 2 % and 3% respectively. How much will be the ,maximum error in the estimate of kinetic energy obtained by measuring mass and speed ?
Options
A.11 %
B.8 %
C.5 %
D.1 %
Solution
K ∝ mv2 ⇒ 
% error in kinetic energy = 2 + 2 (3) = 8%
% error in kinetic energy = 2 + 2 (3) = 8%
