I already did activity 1 can you please do activity 2,3?

Activity 2: The Mass Spectrometer Open the link https'fphyslets_orgwstart_html: select Pan j: Electromagnetism, Chapter 27: Magnetic Fields & F orces, Xlass Spectrometer. A negatively particle enters a region mth a constant magnehc field directed mto dae screen and a constant electric field produced by tiQ charged plates. If the particle is able to pus though the first region (Fm = FE qvB = qE), it enters a region Hhere only dae magnetic field is present: and its treiectory bends. 16. Calculate the magnitude of the electric field needed to select a particle of mass 0.300 g and charge 1.00 X 103 C havmg an mitial velocity of 50 m/s, m a magnetic field of 0.500 T 17. Use the simulation to test your ansuer. Was your calculation correct? I g. Change the value of the magnetic field. Is the 50 mis particle still selected 19. Calculate the velocity of the particle elected for the combinations of electric and magnetic fields magnitude (m die velocity selector region) Ilst&d in Table 2 below. Use the simulation to test answer. In the table, circle or highlight dae result of your test Table 2: Particle ofmass 0.300 g and charge 1.00 X IOa C (Win) 25.0 25.0 25.0 (mfs) sei" fed yes yes yes yes yes yes yes no no no no no no no
