Question
harged Particle and a Uniform Magnetic Field-Force188 The figures below show the circular paths of six charged particles that six different but uniform magnetic fields. The particles have the same mass grven the same initial speed before they entered have been injected into and they were all 1 the field. However, the charges on the particles and the radii of their paths vary Rank these situations from greatest to least on the basis charge of the magnitude of the force on each -,, = 3 cm -' ,' = 4 cm = +5 nC ,r = 2 cm r 2 cm r = 3 cm Greatest I 3 4 Least Or, there is no force on any of these six particles. Or, the ranking for the forces cannot be determined with this information. Please carefully explain your reasoning.
Explanation / Answer
F = qV x B
F = qVBSinQ
for theta 90 degree
F = qVB
F is dependent of charge but independent of radius
F = qVB
Fb = Fe > Fc > Ff > Fa > Fd
