Question
Clear my choice
A horizontal wire of length 3.0 m carries a current of 6.0 A and is oriented so that the current direction is 50° S of W. The Earth's
magnetic field is due north at this point and has a strength of 0.14 × 104 T. What is the direction of the force on the wire?
O a. due east
O b. toward the Earth's surface
O C. 40° S of E
O d. out of the Earth's surface
A proton and an alpha particle are moving perpendicular to a uniform magnetic field with the same speed. If the velocity of the
proton is at an angle of 20° with respect to the magnetic field direction, at what angle to the magnetic field direction would the
alpha particle be moving if it experiences the same magnitude acceleration as the proton? The alpha particle has 4 times the mass
