Q1:

In a perfect prismatic compass

A magnetic axis and geometric axis of the needle coincide

B ends of the needle and pivot are in same vertical and horizontal planes

C pivot is vertically over the centre of the graduated circle

D needle is always kept sensitive

E all the above.

ANS:E - all the above.

I don't think the pivot is over the graduated ring it's centrally under the ring and the agate cap is above that ring.
