Aproton is moving horizontally at 7.9 x 10^5 m/s. it passes through a vertical magnetic field that points downward. in which direction is the proton deflected by the magnetic field? a. up b. to the right of its velocity c. down d. to the left of its velocity

There are four key characteristics of the magnetic force on a moving charge.

First, Its magnitude is proportional to the magnitude of the charge. 
Second, the magnitude of the force is also proportional
Third, the magnetic force depends on the particle’s
velocity. 
Fourth, we find by experiment that the magnetic force  does not have the same direction as the magnetic field  but instead is always perpendicular to both  and the velocity  

So, in a mathematical language this is given by:



So, this is a cross product. Therefore, applying the Right-hand rule:

The answer is:

D. to the left of its velocity.

Explaining this in other words:

"The force  is directed into the plane of the paper, so this is the direction of the proton"

Question was not very clear if there are specific answer choices tell me and i'll try to you more. hope this though2 laps is 1 min. we know that for each min she does two times the amount of laps. for 12 laps we can do 12/2 which does give us 12 laps in 6 mins not 16 mins.

A. they hold atoms  together with a molecule.its a force that exist between molecules. hope this .
