The percentage of error in the measurement of mass and speed are `2% and 3%` respectively. How much will be the maximum error in the estimating kinetic energy obtained by measuring mass and speed?

Text Solution

Verified by Experts

Given, `(Deltam)/(m)xx100=2% and (Deltav)/(v)xx100=3%`
`"Kinetic energy, K"=(1)/(2)mv^(2)`
Percent error in K.E.,
`(Deltak)/(k)xx100=(Deltam)/(m)xx100+2(Deltav)/(v)xx100`
`=2%+2xx3%=8%`
