Question 1 2 pts What path does an electron follow when a uniform magnetic field is orientated perpendicular to the electron's velocity vector? (O Straight line O Zigzag (O Circle (O Helical The goal of this experiment is to measure the ratio e/m for an electron. Which experimentally determined quantities will you need to calculate e/m? (] V - the accelerating voltage (J B - the applied magnetic field [ B_e - the magnetic field generated by the moving electron (] r - the radius of the electron orbit (] E - the excited state energy for mercury atoms Question 3 2 pts How will the electrons be generated? (O Electrons are emitted from a hot cathode (O Electrons are emitted from a hot anode () Electrons are emitted from an electron laser (O Electrons are already floating around inside What type of error is caused by using a meter stick that is worn down to be too short? (O blunder (O definitional () systematic (O random
