The angle of dip at a place is $30^{\circ}$,and the horizontal component of the Earth's magnetic field is $5 \times 10^{-5} \, T$. Calculate the vertical component and the total magnetic field at that place.

  • A
    $5 \times 10^{-5} \, T, 10 \times 10^{-5} \, T$
  • B
    $(5 / \sqrt{3}) \times 10^{-5} \, T, (10 / \sqrt{3}) \times 10^{-5} \, T$
  • C
    $(5 \sqrt{3}) \times 10^{-5} \, T, (10 / \sqrt{3}) \times 10^{-5} \, T$
  • D
    None of the above
