The relations amongst the three elements of earth’s magnetic field namely : horizontal component `H_e` vertical component `V_e` and angle of dip `delta` are (`B_e` = total magnetic field)
Options:
(a) `V_e = B_e tan delta,H_e =B_e`
(b) `V_e =B_e sin delta,H_e = B_e cos delta`
(c) `V_e = B_e cos delta,H_e = B_e sin delta`
(d) `V_e =B_e,H_e =B_e tan delta`
