An electron that has a velocity with x component 1.9 10 6 m/s and y component 3.

Question

An electron that has a velocity with x component 1.9 106 m/s and y component 3.0 106 m/s moves through a uniform magnetic field with x component 0.040 T and y component -0.22 T. (a) Find the magnitude of the magnetic force on the electron. (b) Repeat your calculation for a proton having the same velocity.

(a) Number Units An electron that has a velocity with x component 1.9 x 10^6 m/s and y component 3.0 x 10^6 m/s moves through a uniform magnetic field with x component 0.040 T and y component -0.22 T. (a) Find the magnitude of the magnetic force on the electron. (b) Repeat your calculation for a proton having the same velocity. (a) Number Units Units (b) Number

Explanation / Answer

F = q v x B
= -1.6E-19*<1.9E6, 3.0E6>x<0.04,-0.22>

= 8.608E-14 N

b) since same charge will be same F

8.608E-14 N
