A body travels uniformly a distance of (...

A body travels uniformly a distance of `(13.8+-0.2) m` in a time `(4.0+-0.3) s` so The percentage errors in the problem is

A

`7%`

B

`5.95 %`

C

`8.95 %`

D

`9.85 %`

Text Solution

Verified by Experts

The correct Answer is:
C
`%` error in velocity `= %` error in `L + %` error in `t`
`= (0.2)/(13.8)xx 100 + (0.3)/(4) xx 100`
`= 1.44 + 7.5 = 8.94 %`
