The percentage errors in the measurement...

The percentage errors in the measurement of mass and speed are `2%` and `3%` respectively. The error in kinetic energy obtained by measuring mass and speed, will be

Text Solution

Verified by Experts

`(Deltam)/(m) xx100 =2% , (Deltaupsilon)/(upsilon) xx100= 3%`
Kinetic energy . `E= (1)/(2) mupsilon^(2)`
Maximum error in kinetic energy
`(DeltaE)/(E )xx100= (Deltam)/(m) xx100 + 2(Deltaupsilon)/(upsilon)xx100`
Maximum error in kinetic energy
`= 2% + 2xx3% = 2% + 6% = 8%`
