The percentage errors in the measurement...

The percentage errors in the measurement of mass and speed are `2% and 3%` , respectively . How much will be the maximum error in the estimation of `KE` obtained by measuring mass and speed?

A

0.11

B

0.08

C

0.05

D

0.01

Text Solution

Verified by Experts

The correct Answer is:
B
`K propmv^(2)rArr (DeltaK)/(K)=(Deltam)/(m)+(Deltav)/(v)`
& error in kinetic energy `= 2 + 2(3) = 8 %`
