Statement-1 If error in measurement of distance and time are 3% and 2% respectively, error in calculation of velocity is 5%
Statement-2 : Velocity `= (distance)/(time)`

Options

A. Statement -1 is true, Statement -2 is true , and Statement -2 is correct explanation of Statement -1.
B. Statement -1 is true , Statement -2 is true, but Statement -2 is not a correct explanation of Statement -1.
C. Statement-1 is true, but Statement -2 is false.
D. Statement-1 is false, but Statement -2 is true.

Answer

(b)

Explanation

Both the statements are true. But statement -2 is not a correct explanation of statement -1. Infact
`upsilon = (L)/(T)`
`:. (Delta upsilon)/(upsilon) = +-((Delta L)/(L) + (Delta T)/(T)) = +- (3% + 2%)`
`= +- 5%`
