MCQ
Which error is removed when the known and unknown resistances are interchanged in a Meter Bridge?
- APercentage error
- BMeasurement error
- CEnd error
- DIndex error
✓
Answer
- End error
Explanation:
End error is removed when the known and unknown resistances are interchanged in a Meter Bridge. This additional length has a resistance known as end resistance. So, when an end error arises, it can be removed by interchanging the known and unknown resistances and taking the mean of the resistances determined.

The density of a rod gradually decreases from one end to the other. It is pivoted at an end so that it can move about a vertical axis through the pivot. A horizontal force F is applied on the free end in a direction perpendicular to the rod. The quantities, that do not depend on which end of the rod is pivoted, are:
- Angular acceleration.
- Angular velocity when the rod completes one rotation.
- Angular momentum when the rod completes one rotation.
- Torque of the applied force.
