Q. An electron is projected vertically upward with a speed of 1.30 106 m/s into a uniform magnetic field of 0.280 T that is directed horizontally away from the observer. Describe the electron's path in this field.
Q. Calculate your apparent weight at the top of a Ferris wheel, given that the radius of the wheel is 7.1 , it completes one revolution every 30 , and your mass is 51 .
A proton moves perpendicularly to a uniform magnetic ?eld B with a speed of 1.9 × 10 ^7 m/s and experiences an acceleration of 8 × 10 12 m/s 2 in the positive x direction when its velocity is in the positive z direction. The mass of a proton is 1...
