Answer 2

Given,

The mass of the object is 42.6-0.02 gm

To find,

The percentage error in the measure

Explanation,

Mass of the object=46.2-0.02 gm

It means that here 46.2 gm is the absolute mass and 0.02 is the error in measuring this mass.

For calculating error,

we have to divide 0.02 by 46.2

On dividing ,we get:

0.02/46.2

=-0.00043

Now, for calculating the percentage error, we need to multiply this error by 100.

0.00043* 100

= 0.043%

Therefore, percentage error in measuring this mass is 0.043%.
