Answer Part A Through F Please.

A uniform magnetic field of magnitude is directed along the positive x axis. A positron moving at enters the field along a direction that makes an angle of with the x axis (see figure below). Determine the following: 53.1 a. The parallel and perpendicular components of the velocity with respect to the magnetic field. b. Which of these components is not affected by the filed? Why? c. The initial Kinetic Energy of the positron and its change while in the magnetic field. d. Derive the expression for the radius of the Helix in terms of the given or found quantities, and determine its amount. e. The period and frequency of the positron motion. f. The pitch of the helix, the distance between turns
