Question

a proton is moving horizontally at 7.9 * 10^5 m/s. It passes through a vertical magnetic field that points downward. In which direction is teh proton deflected by the magnetic field?

A. to the left of its velocity
B, to the right of its velocity
C. up
D. down

is this using the fourth right hand rule? :/

Answer 1

yep

Answer 2

since the subsequent vector equation holds:
\[\Large {\mathbf{F}} = - e{\mathbf{v}} \times {\mathbf{B}}\]

Answer 3

ok! what do we plug in? :/

Answer 4

7.9 * 10^5 m/s

Answer 5

F=qvB

Answer 6

hint:

Answer 7

ohh so it is to the right of its velocity is our solution?

Answer 8

yep

Answer 9

the force is pointing to left with respect to the velocity

Answer 10

ohh so choice A is the solution?

Answer 11

yes

Answer 12

that's right!

Answer 13

oops..sorry I have supposed it is an electron

Answer 14

Answer 15

so the right answer is to the right

Answer 16

ooh ok yay! thanks!:)
