11/13/2017 1 1:00 AM 28.6/100 Print Calculator Periodic Table estion 3 of 7 Sapling Learning macmilan learning Determine the direction of the force (if any) that will act on the charge in A positive charge within an electric field that points downward. ative charge within an electric field nat points to the left. A positive charge moving out of the screen in a magnetic field that points to the right. A negative charge moving downward in a magnetic field that points into the screen. A positive charge moving to the right in arn electric field that points into the screen. A negative charge moving downward in a magnetic field that points downward. to the let) into the screen out of the screenzero force downward upward Hint PreviouExplanation / Answer
a). force will act downward along the direction of electric field. if charge is positive
B). force acts rightward opposite to electric field . due to negative charge
c). downward on positive charge F = q(v x B)
D). leftward . force acts left side
E). force will act into the direction of screen along with screen
F). no force acts because angle between velocity and magnetic field is degree.
if you want to find the direction of magnetic force = then put your fingers in the direction of velocity of charge and curl your fingers in the direction of magnetic field then thumb denotes thedirectionof force on the particle. and direction gets opposite in case of negative charge
