Avertical wire carries a current vertically upward in a region where the magnetic field vector points toward the north. what is the direction of the magnetic force on this current due to the field? a) downward b) toward the north c) toward the east d) toward the south e) toward the west two long parallel wires placed side-by-side on a horizontal table carry identical size currents in opposite directions. the wire on your right carries current toward you, and the wire on your left carries current away from you. from your point of view, the magnetic field at the point exactly midway between the two wires a) is zero. b) points upward. c) points downward. d) points away from you. e) points toward you.

Tall pacific coast redwood trees can reach heights of about 100 m. if air drag is negligibly small, how fast is a sequola cone moving when it reaches the ground f it dropped from the top of a 100 m tree?

An charge with mass m and charge q is emitted from the origin, (x,y)=(0,0). a large, flat screen is located at x=l. there is a target on the screen at y position y(h), where y(h) > 0. in this problem, you will examine two different ways that the charge might hit the target. ignore gravity in this problem. 1.assume that the charge is emitted with velocity v(0) in the positive x direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive y direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l. 2.now assume that the charge is emitted with velocity v(0) in the positive y direction. between the origin and the screen, the charge travels through a constant electric field pointing in the positive x direction. what should the magnitude e of the electric field be if the charge is to hit the target on the screen? express your answer in terms of m, q, y(h), v(0), and l.
