Question 11 1 pts What is the direction of the force on the charge in the figure? O To the left O Into the screen O Out of the screen O There is no force O To the right Question 12 1 pts As an airplane flies from Los Angeles to Seattle, it passes through the Earth's magnetic field. As a result, a separation of charge is induced between the wingtips. Which wingtip is negatively charged? In this region, the Earth's magnetic field will have a component pointing towards the North magnetic pole and a component downwards, towards the Earth. O West O East O Neither

Explanation / Answer

magnetic force acting on a charge

F = Q*( v x B )

velocity of the charge v = -vxi + vyj

magnetic field B = -Bx

F = -q*( (-vxi + vyj) x -Bxi )

F = q*vy*Bx (j x i )

F = q*Vy*Bx (-k)

-k is out of page
