A proton,mass 1.67 x 10^-27kg and charge +1.6 x 10^-19 C,moves in a circular orbit perpendicular to a uniform magnetic field of 0.75 T.Find the time for the proton to make one complete circular orbit.

Question

Quizplus · Accepted Answer

The time for one complete circular orbit, also known as the period, can be found using the formula:
T = 2πm/qB
where T is the period, m is the mass of the particle, q is its charge, and B is the magnetic field.
Substituting the given values, we get:
T = 2π(1.67 x 10^-27 kg)/(1.6 x 10^-19C)(0.75 T)
T = 8.7 x 10^-8 s
Therefore, the correct choice is B).
