Answer 2

Answer:

qb/2πm

Explanation:

Force on a charge q moving with velocity v in a magnetic field b is given by:

F=q  (V x B)

where we take cross product of velocity and magnetic field vectors.

Now F=qvb (since v is perpendicular to b)

This force provides the centripetal force required for circular motion,

therefore qvb=mv²/r     ⇒⇒⇒⇒⇒⇒⇒1

From this we get r=mv/qb which is the radius.

From this time period= distance / speed for 1 revolution

⇒T=2πR/ v =2πm/qb

we can get value of velocity from  equation 1

and as you might know, frequency is just inverse of Time period

⇒F=qb/2πm
