Assertio: When percentage errors in the ...

Assertio: When percentage errors in the measurement of mass and velocity are 1% and 2% respectively, the percentage error in K.E. is 5%
Reason: `(DeltaK)/(K)=(Deltam)/(m)+(2Deltav)/(v)`

A

If both Assertion and Reason are correct and Reason is the correct explaination of Assertion.

B

If both Assertion and Reason are correct but Reason is not the correct explaination of Assertion.

C

If Assertion is true but Reason is false.

D

If Assertion is false but Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
A
KE = `(1)/(2)mv^(2)rArr(DeltaE)/(E)=(Deltam)/(m)+(2Deltav)/(v)`
`rArr(DeltaE)/(E)xx100=((Deltam)/(m))xx100+2((Deltav)/(v)xx100)=1+2(2)=5%`
