Question

A positively charged particle falls vertically downwards. The horizontal component of earth magnetic field will deflect it towards

Answer 1

Answer:

negatively charged particle

Answer 2

Answer:

The horizontal component will deflect towards east.

Explanation:

Magnitude of the magnetic force on a charged particle moving in a magnetic field is expressed by the below following formula.

$F_{B}=q v B \sin \theta$

Since the particle is moving vertically, the angle is $90\degree$. Using the right hand rule the direction of velocity symbolised by the thumb is downwards. The palm has to be open. The direction of B is also towards north just like velocity.

The magnetic force will be represented by the direction you wold push your open hand which is the east.
