What is the need for modulation ?

Derive an expression for the angle of bending of a cyclist on a curved track.

A cloud chamber photograph shows a pair of circular tracks emerging form a common point. The tracks have similar density of droplets, but curve in opposite directios in a plane normal to the magnetic field maintained in the chamber. If one of the ionizing particles is established to be an electron, guess the hgih energy event that took place at the common point of the track.

What is the need for vectors?
