Balanced eq.:-  P + 5HNO₃ → 5NO₂ + H₂O + H₃PO₄

Hence Balanced eq. :- P + 5HNO₃ → 5NO₂ + H₂O + H₃PO₄ Physics 12 Moving Charges and Magnetism

A positively charged particle projected towards east is deflected towards north by a magnetic field. The field may be :

A: towards west

B: towards south

C: upwards

D: downward

The direction of the positive charge particle towards east and hence the current's direction and the direction of the force towards north.

Now by applying Fleming left hand rule we can say that the direction of the field towards downward.

Hence, the correct option is (D). ( downward )
