Each of the lettered points at the corners of the cube in Fig. Q27.12 represents a positive charge q moving with a velocity of magnitude v in the direction indicated. The region in the figure is in a uniform magnetic field B S , parallel to the x@axis and directed toward the right. Which charges experience a force due to B S ? What is the direction of the force on each charge?
Physics 213 // Week 3 Notes PSU Spring Term, 2017 _______ = Formula Chapter 34 Notes Q: What is an image (relating to images of physics) A: An image is a reproduction of an object via light. Q: How can we relate the object’s distance to a mirror and the reflected image A: = − (plane mirror formula) i = image distance (meters) p = distance from object to mirror (meters) Q: How can you tell if an image is virtual A: If ‘i’ is negative (-i) then the image is virtual. If ‘i’ is positive (+i) then the image is real. Q: Can a convex mirror form a real image A: No! Convex mirrors can only form virtual images. Q: Can a concave mirror form a real image A: Y
