Question

arises when the reading of a scale is taken from a random angle.

• A. Zero error
• B. Angle error
• C. Parallax error
• D. Numerical error

Answer 1

The correct option is C Parallax error

Parallax error arises when the reading is taken from a random angle instead of taking at any specified angle. There is a difference in the readings if the readings are taken at different angles. So to avoid this error we must always take the readings by positioning our sight just perpendicularly above the markings.
