Question

Please include work. I'd like to know how to solve them.

1.) Consider a charged particle moving through a region in which the electric field is perpendicular to the magnetic field, with both fields perpendicular to the initial velocity of the particle (see figure below). Such a device is called a velocity selector because for one particular value of the particle speed vselect the particle will travel straight through the device without being deflected, whereas particles with speeds that are either less than or greater than vselect will be deflected. Consider a case with E = 525 V/m and B = 0.28 T.

_______m/s

(b) What is the speed selected for Ca²⁺ ions?
_____m/s

thank you so much for your help!!

Answer 1

A) at equilibrium F_{E =} F_B ie qE = qVB Or V = E/B = 525/0.28 = 1875 m/s

B) Speed will remain same as it doesn;t depend upon charge
