Aproton, mass 1.67 · 10 27 kg and charge +1.6 · 10 19 c, moves in a circular orbit perpendicular to a uniform magnetic field of 0.71 t. find the time for the proton to make one complete circular orbit.

Time,

Explanation:

It is given that,

Mass of proton,

Charge on proton,

Magnetic field, B = 0.71 T

Time taken by proton to make one complete circular orbit is given by :

So, the time for the proton to make one complete circular orbit is  . Hence, this is the required solution.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
