What is the velocity of a beam of electrons that goes undeflected when passing through perpendicular electric and magnetic fields of magnitude e= 8. 4 kv/m and b=7. 5 mt? give answer in m/s.

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

no

explanation:

no i dont know how to solve this you should probably try to google the answer
