Percentage erros in the measurement of mass and speed are 2% and 3% respectively. The error in the estimation of kinetic energy obtained by measuring mass and speed will be:

`11%`

`8%`

`5%`

`1%`

Text Solution

Verified by Experts

The correct Answer is:

`E=(1)/(2)mv^2`
`%` Error in K.E.
`=%` error in mass`+2xx%` error in velocity
`=2+2xx3=8%`
