1. A beam of protons (q = 1.6x10-19 C) moves 3.0x108 cm/s through a uniform 5.0-T magnetic field directed along the positive z-axis. The velocity of each proton lies in the xz-plane and is directed at 40° to the +z-axis. Find the force on a proton.

1. An electron has a velocity v = (2 x 106 m/s) i +(3.0x 106 m/s)j moves through a uniform magnetic field B = (0.030 T) ? - (0.15 T)j. (a) Find the force on the electron due to the magnetic field. (b) mass of electron is 9.11 x 10-31 kg what will be the radius of the circular path for the electron in the magnetic field?

2. An electron is instantaneously located at the origin and had a velocity of i = (5.0 x 107,0.0,0.0)m/s. At this moment, find the vector magnetic field at the two locations: (3.0,4. 0,0. 0)m and (5.0,0.0,0.0)m. Express your answer as a vector.

5. A conductor carrying a current I = 10.0 A is directed along the negative x axis and perpendicular to a uniform magnetic field. A magnetic force per unit length of 0.2 N /m acts on the conductor in the negative Z Determine (a) the magnitude and (b) the direction of the magnetic field in the region through which the current passes
