Question

Thickness of the paper measured by micrometer screw gauge of least count 0.01 mm is 1.03 mm, the percentage error in the measurement of thickness of paper isA. 1.1%
B. 1%C. 0.97%
D. 0.8%

Answer 1

Answer ⇒ Option (C). 0.97 %

Explanation ⇒

Given conditions ⇒

Least Count = 0.01 mm

Thickness of the Paper = 1.03 mm.

% Error = Least Count/Measured Thickness × 100

= 0.01/1.03 × 100

= 0.97 %

Hence, the Option (C). is correct.

Hope it helps.

Answer 2

Answer:

Option C  0.97%

Explanation:

Thickness of the paper measured by micrometer screw gauge of least count 0.01 mm is 1.03 mm, the percentage error in the measurement of thickness of paper is

A. 1.1%  

B. 1%

C. 0.97%  

D. 0.8%

Least count = 0.01 mm

1.03 can be    1.025  or 1.035

Maximum Error = 1.035 - 1.025 = 0.01

Error % = (0.01/1.03) * 100 =  0.97%

Option C  0.97% is correct

Or simply = (least Count/Reding) * 100 %

= (0.01/1.03) * 100

= 1/1.03

= 0.97 %
