How long does it take a proton (mp = 1.67 x 10^-27 kg) moving in an orbit perpendicular to a magnetic field of 2 t to complete one circular orbit?

Explanation:

Given

mass of proton

Magnetic Field(B)=2 T

Required centripetal Force to move in a circle is provided by magnetic field

=qvB

Where q=charge of proton

B=magnetic Field

v=Velocity of Charge

=Angular velocity

i dont think you are wrong for wanting to get even with someone who did you wrong.

(i'm an eye for an eye kind of person) but if this person hurt you in a sexual way, i dont suggest doing anything to him. he should be taken to the proper authorities, you could go to jail depending on what you do. if it was something small like your sibling took your spot on the couch, than yea, i would get even with him by taking one of his favorite snacks lol. but i dont suggest you doing anything illegal.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
