NEET Physics Screw Gauge MCQ Question
Type: MCQ-fact-Medium-Class 12
What is the formula to calculate the thickness of a sheet using a screw gauge?
A
d = M + n × L.C.
B
d = M - n × L.C.
C
d = M × n + L.C.
D
d = M / n + L.C.
Correct Answer
Option A
Detailed Explanation
The thickness of a sheet measured by a screw gauge is calculated using the formula d = M + n × L.C., where M is the linear scale reading, n is the circular scale reading, and L.C. is the least count.
