Question

If the percentage error in the measurement of momentum and mass of an object are2% and 3%respectively ,then maximum percentage error in the calculated value of its kinetic energy is

Answer 1

Answer:

7 %

Explanation:

% error in momentum = 2%

A^p *100 = 2%

% error in mass = 3%

A^ n * 100 = 3%

KE = 1^2 mv square

P= mv

V=p^m

KE = 1^2 m ( p^m) whole square

KE= p Square. ^ 2m

KE^ KE*100

(2) (2) + 3

4 + 3
