Question

Given below are two statements:one is labelled as Assertion (A) and the other is labelled as Reason (R).\ Assertion (A) : In Vernier calliper if positive zero error exists, then while taking measurements, the reading taken will be more than the actual reading.\ Reason (R) : The zero error in Vernier Calliper might have happened due to manufacturing defect or due to rough handling.\ In the light of the above statements, choose the correct answer from the options given below.\

Professor PC Thomas Classes · Answer

(d) : Assertion : Reading $=$ Total Reading - Zero Error\ So, assertion is correct.\ Also, the zero error in vernier callipers arises due to manufacturing defect or due to rough handling. So reason is also correct but does not explain assertion.\ So, assertion and reason both are correct and reason is not the correct explanation of assertion.\ So, option (d) is correct.\
