An proton is traveling in the -X direction and is slowing down. What is the direction of the E-field in this situation?

An electron with initial velocity vo = 1.96 x 105 m/s enters a region 1.0 cm long where it is electrically accelerated (see the figure). It emerges with velocity v = 5.04 x 106 m/s. What is its acceleration, assumed constant? (Such a process occurs in conventional television sets.)

A particle with charge q and and speed venters a region of magnetic field B1 and is deflected from its path into a region with field B2. It enters the second region moving vertically and exits horizontally.   a) Draw a sketch of the path of the particle. b)The particle exits the second region at a height d, measured from the interface of the two regions. What is the mass of the particle?

A cyclotron designed to accelerate protons has an outer radius of 0.45 m. The protons are emitted nearly at rest from a source at the center and are accelerated through 700 V each time they cross the gap between the 'dees'. The dees are between the poles of an electromagnet where the field is 0.69 T. a. Find the speed at which protons exit the cyclotron (proton mass = 1.67×10-27). b. Find the cyclotron frequency f for the protons in this cyclotron (Hint: v=r.(2Ã)). c. Calculate the maximum kinetic energy of the proton?

A particle with mass m and charge –q is suspended when the electrical force field E balances the gravitational force field g. m × g = q × E. Under the same conditions, in which direction does a particle with mass 2m and charge –q move? up, neither, down

What is the radius of its path?

Air breaks down (loses its insulating quality) and sparking results if the field strength is increased to about 3.0 x 106 N/C. a) What acceleration does an electron experience in such a field (me=9.11x10’31kg)? (b) if the electron starts from rest, in what distance does it acquire a speed equal to 10% of the speed of light (3x107 m/s)?

A cyclotron (figure) designed to accelerate protons has an outer radius of 0.333 m. The protons are emitted nearly at rest from a source at the center and are accelerated through 572 V each time they cross the gap between the dees. The dees are between the poles of an electromagnet where the field is 0.720 T.
