Question 1:

An electron with a velocity v = 5 x 10 i m/s enters a region in which the electric field is E = -300 j V/m. a) What is the magnetic field required for the electron not to be deflected? B b) If the electric field is switched off, what is the radius of the path in the magnetic field? cmX X X X X X X X X X What is the velocity must a proton have if it is to go undeflected when passing through a magnetic field of B= 3.3 Tesla which is crossed with an electric field of E= 11100 V/m? Here, the E-field is the red arrows, and the B-field is the blue crosses. So the E-field points down and the B- field points into the screen. The proton is the black dot, moving with some speed v shown by the black arrow. The velocity is equal to ?B d A particle is shot into a magnetic field region as shown in the figure. If the particle is shot in with a speed of v = 213 m/s, has a charge of q = 36.7 /C and a mass of m = 2.7 mg, how strong must the magnetic field be so the particle just misses the right plate, given that the plates are separated by a distance d = 0.17 m? The magnetic field is equal to V
