In the velocity selector the electric field is 90,000V/m down and the magnetic field is 0.0053T into the page. An electron is shot through the velocity selector and then enters a region of a magnetic field that has a strength of 0.00242T into the page. If the radius of curvature of the electron is 4 cm . Calculate the mass of the electron.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
