Questions
A magnetic needle is oscillating in earth’s horizontal field with a time period of 0.5 sec. A dip needle of same magnetic dipole moment, mass and geometry oscillator in earth’s vertical field with a time period of 1 sec. Then angle of dip at that place is
detailed solution
Correct option is D
T1=2πIMBH and T2=2πIMBV∴ T1T2=BVBH=tanδ⇒tanδ=T1T22=0.512=14⇒δ=tan−114Talk to our academic expert!
