Question

the percentage error's of measurement in velocity and mass are 2% and 6%. what is the percentage error in kinetic energy ?​

Answer 1

Answer:

Given percentage errors in mass and velocity = 2% and 3% respectively

The kinetic energy of the particle is given by

KE =

2

mv

2

The percentage error in kinetic energy will be

m

Δm

×100+2

v

Δv

×100

= 2+6

= 8%
