Question

While measuring the length of the rod by vernier callipers the reading on the main scale is 6.4cm and the 8th division on the vernier in line with marking on main scale division. If the least count of callipers is 0.01cm and zero error - 0.04cm, find the length of the rod ​

Answer 1

Answer:

6.52 cm

Ms= 6.4

VS = 0.01x8 = 0.08

ZE = -0.04

Actual = 6.4 +0.08 + 0.04 = 6.52

LEARN : Negative zero error refers to the case when the jaws of the vernier caliper are just closed and the reading is a negative reading away from the actual reading of 0.00 mm. If the reading is 0.08 mm, the zero error is referred to as -0.08 mm. ..

If negative, the error is added to the mean reading the instrument reads.
