A beam of electrons is accelerated through a potential difference of 12.0 kV before entering a velocity selector. If the B-field of the velocity selector is perpendicular to the velocity and has a value of 0.02 T, what value of the E-field is required (in the magnetic field region) if the particles are to be undeflected? It's not 1.949*10^6.

A beam of electrons is accelerated through a potential difference of 10 kV before entering a region having uniform electric and magnetic fields that are perpendicular to each other and perpendicular to the direction in which the electron is moving. If the magnetic field in this region has a value of 0.010 T, what magnitude of the electric field is required if the particles are to be undeflected as they pass through the region?

A proton (m= 1.67e-27 kg) is accelerated from rest through a potential difference of 11.5 kV before entering a velocity selector. If the B- field of the velocity selector is perpendicular to the velocity and the electric field (E) has a magnitude of 3.5e6 N/C, what is the required magnitude of the magnetic field (B) if the proton is undeflected?

A beam of protons is accelerated through a potential difference of 0.750 kV and then enters a uniform magnetic field traveling perpendicular to the field. Part A: What magnitude of field is needed to bend these protons in a circular arc of diameter 1.76 m ? B = ____ T Part B: What magnetic field would be needed to produce a path with the same diameter if the particles were electrons having the same speed as the protons? B' =...

An electron is accelerated through a potential difference of 2.2 kV and directed into a region between two parallel plates separated by 20 mm with a potential difference of120 V between them. The electron is moving perpendicular to the electric field when it enters the region between the plates. What magnetic field is necessary perpendicular to both the electron path and the electric field so that the electron travels in a straight line? T
