Term
| The path of a charged particle (whether its a proton or electron) moving in a plane perpendicular to a uniform electric field is always a ____ path. |

|
Term
| T or F: force is always perpendicular to the velocity |

|
Term
| t or f: a charged particle moving in an magnetic field has a constant velocity |
|
Definition

|
Term
| give the formula for the accleration of a charged particle moving in an magnetic field |
|
Definition
a = v2/r
centripetal acceleration b/c charged particle is moving in a circular path |
|
|
Term
| true or false: a charged particle moving in an magnetic field has a constant centripetal acceleration? |

|
Term
for a given inital velocity,
↑ massive particle, has a (longer/short) period of revolution when moving in a magnetic field |
|
Definition
↑ massive particle
= longer period
why?
a more massive particle will travel in a cricle with a wider radius and thus it will take longer to complete one revolution. |
|
|
Term
| ↑ massive particle, has a (longer/short) frequency of revolutions when moving in a magnetic field |
|
Definition
↑ massive particle=
↓number of revolutions
(b/c it takes a long time to complete one go around as it is.)
or recall period= 1/f
so if periods are longer then frequencies are less |
