A wire along the z-axis carries a current of 6.8 A in the +z direction. Find the magnitude and direction of the force exerted on a 6.1-cm long length of the wire by a uniform magnetic field with magnitude 0.36 T in the -x direction.
 
  What will be an ideal response?

Question 2

A slide projector needs to focus the image of a 24.0-mm  36.0-mm slide onto a square screen 1.50 m on each side. You want to fill the screen as completely as possible without any of the image falling beyond the screen.
 
  Due to space constraints in the projector, the slide must be placed 10.5 cm from the lens. (a) What magnification does the projector produce? (b) How far from the lens should the screen be placed? (c) What focal length projector lens is needed?
