The angle of dip at a place is 37^ and the vertical component of the earth's magnetic field is 6 10⁻⁵ ~T . The earth's magnetic field at this place is ( 37^ = 3 4 )
Options
- A7 10⁻⁵ ~T
- B6 10⁻⁵ ~T
- C5 10⁻⁵ ~T
- D10⁻⁴ ~T
Correct answer
D. 10⁻⁴ ~T
Step-by-step solution
= V H = 3 4 [ 37^ = 3 4 ] V = 3 4 H V =6 10⁻⁵ ~T H = 4 3 6 10⁻⁵ ~T =8 10⁻⁵ ~T B _ total = V ²+ H ² = (36+64) 10⁻⁵=10 10⁻⁵=10⁻⁴ ~T .
