Question

The percentage error in the measurement of mass and speed are 2% and 3%, respectively.hox much will be the maximum error in kinetic energy? A) 1% B) 5% C) 8% D) 12% C) 2.16 If unit of length and for aro increased 4 times The unit of 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%
