At the equator, near the surface of the Earth, the magnetic field is approximately 50.0 µT northward, and the electric field is about 100 N/C downward in fair weather. Find the gravitational, electric, and magnetic forces on an electron in this environment, assuming that the electron has an instantaneous velocity of 5.00 × 106 m/s directed to the east. gravitational force 9.010 X N directed downward v electric force N directed upward magnetic force -4 X N directed downward v

A proton moving at 4.50 x 106 m/s through a magnetic field of magnitude 1.68 T experiences a magnetic force of magnitude 8.40 x 10-13 N. What is the angle between the proton's velocity and the field? (Enter both possible answers from smallest to largest.)

(d) Would the electron undergo the same acceleration? O Yes O No

A proton travels with a speed of 4.90 x 106 m/s at an angle of 62° with the direction of a magnetic field of magnitude 0.240 T in the positive x-direction. (a) What is the magnitude of the magnetic force on the proton? N (b) What is the proton's acceleration? m/s²

A proton moving at 4.30 x 10° m/s through a magnetic field of magnitude 1.62 T experiences a magnetic force of magnitude 8.80 x 105 N. What is the angle between the proton's velocity and the field? (Enter both possible answers from smallest to largest.)

A beryllium-9 ion has a positive charge that is double the charge of a proton, and a mass of 1.50 ✕ 10−26 kg. At a particular instant, it is moving with a speed of 5.10 ✕ 106 m/s through a magnetic field. At this instant, its velocity makes an angle of 62° with the direction of the magnetic field at the ion's location. The magnitude of the field is 0.220 T. (a) What is the magnitude of the magnetic force (in N) on the ion?                         N (b) What is the magnitude of the ion's acceleration (in m/s2) at this instant?                          m/s2

A proton, traveling with a velocity of 2.5 × 106 m/s due east, experiences a magnetic force that has a maximum magnitude of 5.1 × 10-14 N and direction of due south. What are the magnitude and direction of the magnetic field causing the force? If the field is up, then enter a number greater than zero. If the field is down, then enter a number less than zero.
