Question

A dip circle is so set that its needle moves freely in the
magnetic meridian. In this position, the angle of dip is 40º.
Now the dip circle is rotated so that the plane in which the
needle moves makes an angle of 30º with the magnetic
meridian. In this position, the needle will dip by an angle
(a) 40º (b) 30º
(c) more than 40º (d) less than 40º

Answer 1

Explanation:

HEY MATE HERE IS YOUR ANSWER

δ 1 =40 o ,δ 2 =30 o cotδ= cot 2 δ 1 +cot 2 δ 2 = cot 2 40 o +cot 2 30 o cotδ= 1.19 2 +3 =2.1∴δ=25 o i.e.δ<40 o

ANSWER IS 40
