JEE Main 2022 — Magnetic Properties of Matter Question with Solution

JEE Main 2022 (29 Jul Shift 2)

Question

The vertical component of the earth's magnetic field is 6×10-5 T at any place where the angle of dip is 37°. The earth's resultant magnetic field at that place will be (Given tan37°=34)

Show full solutionCorrect option: D
Correct answer
D1×10-4 T

Step-by-step explanation

Given here:

The vertical component of the earths magnetic field BV=6×10-5 T and angle of dip δ=37°.

For vertical component, BV=Bsinδ

Putting the values, we have 

⇒6×10-5=B35

Earth's magnetic field at that place as B=10×10-5 T =10-4 T
