Type: MCQ-numerical-Hard-Class 12
If the total magnetic field of the earth at a place is 0.39 G and the angle of dip is 35°, what is the horizontal component of the earth's magnetic field at that location?
A
0.32 G
B
0.23 G
C
0.35 G
D
0.27 G
Correct Answer
Option A
Detailed Explanation
The horizontal component of the earth's magnetic field can be calculated using the formula B_H = B * cos(θ), where B is the total magnetic field (0.39 G) and θ is the angle of dip (35°).
