Question

Why should we pivot the compass needle on a sharp pin?
A) To minimize the magnetic effect on the pin B) To maximize the magnetic effect on the pin C) To minimize the friction between the pin and the compass needle D) To ensure that the compass needle will not drop from the pivoted point

Answer 1

the correct is D. to ensure that the compaa needle will not drop from the pivoted point

Answer 2

Answer:

The answer is Option number D)
