What is the frequency of the circular orbit for an electron with speed 1. 0×106m/s? assume that the electron moves in a plane perpendicular to the magnetic field.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

another example of kinetic energy would be,

kinetic energy   >     moving energy

hope that !                                         : )
