the diagram shows a positive charge moving in a magnetic field. in which direction is the magnetic force acting on the charge? into the screen out of the screen up down

the diagram shows a positive charge moving in a magnetic field. in which direction is the magnetic force acting on the charge? into the screen out of the screen up down

Answer

Explanation:

Step1: Apply right - hand rule

Point the fingers of your right hand in the direction of the velocity ($v$) of the positive charge (to the right). Curl your fingers in the direction of the magnetic field (out of the page as the dots represent a magnetic field coming out of the page). Your thumb will point in the direction of the magnetic force.

Step2: Determine the force direction

When you perform the right - hand rule as described above, the thumb points down.

Answer:

down
