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.
Definition
 circular
Term
 T or F:  force is always perpendicular to the velocity
Definition
 true
Term
 t or f: a charged particle moving in an magnetic field has a constant velocity
Definition
 true
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?
Definition
 true
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
