In a mass spectrometer, a specific velocity can be selected from a distribution by injecting charged particles between a set of plates with a constant electric field between them and a magnetic field across them (perpendicular to the direction of particle travel). if the fields are tuned exactly right, only particles of a specific velocity will pass through this region undeflected. consider such a velocity selector in a mass spectrometer with a 0.095 t magnetic field. part (a) what electric field strength, in volts per meter, is needed to select a speed of 41 106 ms? 50% part (b) what is the voltage, in kilovolts, between the plates if they are separated by 0.75 cm?

Give me some answer choices and i will be happy to

Hello,the answers iron,  hope this

The correct answer for the first question is a. because if cold air is denser then the warm air will be pushed out of the way. the coreect answer for the 2nd question is a.
