Given `P=0.0030 m, Q=2.40 m, R=3000 m`, Significant figures in `P, Q` and `R` are respectively

A

(a)` 2, 2, 1`

B

(b)` 1, 3, 4`

C

(c )` 4, 2, 1`

D

(d)` 4, 2, 3`

Text Solution

Verified by Experts

The correct Answer is:
B
Given `P=0.0030 m, Q= 2.40 m` and `R=3000 m` In `P(0.0030)` initial zeros after the decimal point are not significant. Therefore, significant figures in `P(0.0030)` are 2. Similarly in `Q(2.40)` significant figures are 3 as in this case final zero is significant. In `R=(3000)` all the zeroes are significant hence, in R significant figures are 4.
