An analytic balance has uncertainty in m...

An analytic balance has uncertainty in measurement equal to `+- 1 mg`. Then report the result in terms of percentage if the weight of a compound is
a. `1 g` b. `10 g` c. `100 g`

A

one roots is less than 0, the is posititve, the other is negative.

B

exactly one of the roots lies in (0,1)

C

both the roots lie in (0,1)

D

at least one of the roots lies in (0,1)

Text Solution

Verified by Experts

The correct Answer is:
1
`af(1) lt 0 and f(0) f(1) gt 0`
`rArr af(1) lt 0 and af(0) lt 0`
Hence, both the numbers 0 and 1 lie between the roots.
