Question

An upward force acts on a proton as it moves with a speed of 2.0 × 105 meters/second through a magnetic field of 8.5 × 10-2 tesla running from east to west. What is the force and direction of the force on the proton?
Select one of the options below as your answer:

A.
2.7 × 10-15 N to the north
B.
2.7 × 10-15 N to the south
C.
1.7 × 10-14 N to the north
D.
1.7 × 10-14 N to the south
E.
1.7 × 10-14 N downward

Answer 1

its B correct n to south

Answer 2

F=bqv sin(angle b/w vel vector nd direction of mag field)

Answer 3

can u send it to me plugged in or just some im having trouble with that...:/

Answer 4

\[F=q\vec{v}\times\vec{ B}\]
here q=charge
v=velocity
B=magnetic field

Answer 5

ok thanks

Answer 6

:)
