An electron enters a region that contains a magnetic field directed into the page as shown. The velocity vector of the electron makes an angle of 30° with the +y axis. What is the direction of the magnetic force on the electron when it enters the field?

A 10 micro-Coulomb charge moves in the X-Y plane with a velocity 5x10° m/s making an angle of 60° with the x-axis. If a magnetic field of 2 T is applied along the +y axis, the magnetic force on the electron is

An electron moves in a circular path perpendicular to a magnetic field of magnitude 0.215 T. If the kinetic energy of the electron is 4.20 × 10-19 J, find the speed of the electron and the radius of the circular path. (a) the speed of the electron m/s (b) the radius of the circular path μm

An electron is moving to the right when suddenly a magnetic field is switched on that points out of the page. Describe the resulting path of the electron. O a clockwise circle in the plane of the page O a circular path coming out of the page on the right and into the page on the left O a counterclockwise circle in the plane of the page O a straight line O a circular path coming out of the page on the left and into the page on the right
