If the length of rod A is 3.25 `pm` 0.01 cm and that of B is 4.19 `pm` 0.01 cm then the rod B is longer than rod A by

A

`0.94 pm 0.00 cm`

B

`0.94 pm 0.01 cm`

C

`0.94 pm 0.02 cm`

D

`0.94 pm 0.005 cm`

Text Solution

Verified by Experts

The correct Answer is:
C

`A = (3.25 pm 0.01)cm, B = (4.19 pm 0.01)cm`
`B - A = (0.94 pm 0.02)cm.`
