An unknown charged particle passes without deflection through crossed electric and magnetic fields of strengths 187,500 V/m and 0.1250 T, respectively. The particle passes out of the electric field, but the magnetic field continues, and the particle makes a semicircle of diameter 25.05 cm. What is the particle's charge-to-mass ratio? Can you identify the particle? can't identify proton electron neutron

elp with physics 102 An electron moves through a region of crossed electric and magnetic fields. The electric field E = 2 000 V/m and is directed straight down. The magnetic field B = 0.80 T and is directed to the left. Specify the directions of electric and magnetic forces on the electron if it moves into the paper. For what velocity v of the electron will the electric force exactly cancel the magnetic force? A rod(length = 10 cm)...

What is the radius of the electron orbit if the electric field is turned off? [hint: start with Newton’s 2nd law to derive an equation and then do the calculation]
In a common type of mass spectrometer, a beam of ions is passed through a velocity sector with crossed electric and magnetic fields. What is the purpose of the velocity sector? to strip loose electrons from the ions to decrease the kinetic energy of the ions to prevent the ions from traveling in a circular path to block all ions except those with specific speeds
