Aproton, traveling with a velocity of 4.6 × 106 m/s due east, experiences a magnetic force that has a maximum magnitude of 6.0 × 10-14 n and direction of due south. what are the magnitude and direction of the magnetic field causing the force? if the field is up, then enter a number greater than zero. if the field is down, then enter a number less than zero.

since the direction of force is along south so the magnetic field must be upwards

Explanation:

Force on moving charge in magnetic field is given as

here we know this is force on proton

so we have

also we know that the velocity of charge is

now from above formula we have

since the direction of force is along south so the magnetic field must be upwards

b.

explanation:

10.0

scientific laws are the result of testing theories and proving them to be facts.
