A uniform magnetic field of magnitude 0.165 T is directed along the positive x axis. A positron moving at a speed of 4.95 Times 10^6 m/s enters the field along a direction that makes an angle of theta = 85.0 degree with the x axis (see figure below). The motion of the particle is expected to be a helix. Calculate the pitch p of the trajectory as defined in figure. Calculate the radius r of the trajectory as defined in...

In a vacuum, a proton (charge = +e, mass = 1.67 x 10-27 kg) is moving parallel to a uniform electric field that is directed along the +x axis (see figure below). The proton starts with a velocity of +4.40 x 104 m/s and accelerates in the same direction as the electric field, which has a value of +7.90 x 103 N/C. Find the velocity of the proton when its displacement is +2.0 mm from the starting point. +2.0 mm...
