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?

`11%`

`8%`

`5%`

`1%`

Text Solution

Verified by Experts

The correct Answer is:

`E= (1)/(2)mv^(2)`
`% "eroor in mass" + 2 xx % "error in velocity"`
`= 2 + 2 xx 3 = 8%`
