Question

question 1:

question 2: A proton is moving at 2.00×105 m/s and begins to circle at a radius of 4.000e-3 m. What is the strength of the perpendicular magnetic field acting on the proton? please give me the answer in T.

question 3:

question 1: A doubly ionized molecule is studied in a mass spectrometer, where it is accelerated through a potential difference of 410 V and found to travel in a circular path of radius 7.70 cm in a 0.460-T magnetic field. What is the molecule’s mass?

question 2: A proton is moving at 2.00×105 m/s and begins to circle at a radius of 4.000e-3 m. What is the strength of the perpendicular magnetic field acting on the proton? please give me the answer in T.

question 3:

question 3: At what speed will a particle of mass 9.7×109 kg and charge 27 nC move in a circular path of radius 5.2 cm in a uniform 2.2-T magnetic field?

Explanation / Answer

question3)

0.5mv2 = q(vB)r

v=2qBr/m

v=2*27*10^-9 *2.2*0.052/9.7*10^-9

v=0.637 m/s
