At a certain place, the angle of dip is 60^ and the horizontal component of the earth's magnetic field (B_H ) is 0.8 10⁻⁴ ~T . The earth's overall magnetic field is
Options
- A1.5 10⁻⁴ ~T
- B1.6 10⁻³ ~T
- C1.5 10⁻³ ~T
- D1.6 10⁻⁴ ~T
Correct answer
D. 1.6 10⁻⁴ ~T
Step-by-step solution
Given, aligned B_H & =0.8 10⁻⁴ ~T & =60^ B_e & =? aligned We know that, aligned B_H & =B_e 0.8 10⁻⁴ & =B_e 60^ aligned aligned B_e & = 0.8 10⁻⁴ 1 2 & =1.6 10⁻⁴ ~T aligned
