Pr1. The figure shows the cross-section of a long, straight, cylindrical
coil (solenoid) of radius r = 10 cm. The number of turns per unit length is
n = 500 m-1. A direct current I = 1,0 A flows clockwise in the solenoid.
A charged particle accelerated by a voltage 1000 V enters into the solenoid
through a gap between the coils at point A. The velocity of the particle
at point A is pointing along the radius. The particle is traveling inside
the solenoid in a plane perpendicular to its axis and exits at point C at
an angle a = 60° to its initial direction.
