Aproton travels with a speed of 4.2×106 m/s at an angle of 30◦ west of north. a magnetic field of 2.5 t points to the north. find the magnitude of the magnetic force on the proton. (the magnetic force experienced by the proton in the magnetic field is proportional to the component of the proton’s velocity that is perpendicular to the magnetic field.)

Explanation:

The magnitude of the magnetic force on the proton is given by:

where:

is the proton charge

is the proton velocity

is the magnetic field

is the angle between the direction of v and B

Substituting into the formula, we find

No hablo español bien, pero según el modelo estándar de Big Bang, el universo nació durante un período de inflación que comenzó hace unos 13.800 millones de años.

¡¡espero que esto ayude!!
