What is backlash error ? Why is it caused ?

Assertion (A): Backlash error can be minimised by turning the screw in one direction only when fine adjustment is done. Reason (R ): Backlash error is caused due to wear and tear or loose- fittings in screws.

Assertion (A): In searle's experiment, it is better to start the experiment with some initial load on the hanger. Reason (R ): In searle's experiment, it is desirable that wire is straight and no kinks are there.
