NEET Physics Earth's Magnetism MCQ Question
Type: MCQ-numerical-Medium-Class 12
If the earth's magnetic field at a place is 0.39 G with an angle of dip of 35°, what is the vertical component of the earth's magnetic field at that location?
A
0.22 G
B
0.27 G
C
0.32 G
D
0.33 G
Correct Answer
Option B
Detailed Explanation
The vertical component of the earth's magnetic field is calculated using Bv = B * sin(δ). With B = 0.39 G and δ = 35°, Bv = 0.39 * sin(35°) ≈ 0.27 G.
