PHYS 202 Midterm: PHYS 202 TAMU 202s07 Exam 2
Document Summary
No work need be shown and no partial credit will be given. (5 pts) 1. A small object with negative charge is in a region of uniform electric field. The force that the electric field exerts on the object is in the +1 direction. \vhat is the direction of the electric field? (a) +x (b) x (c) +y (d) y (. 5 pts) 2. There is a uniform electric field in the -i-x direction. 0. 20 m and point b is at the origin. Which statement about the potentials va and v, at these two points is correct? (a) va 4, (c) (5 pts) 3. A small object with negative net charge moves from point a to point b. The potential at a is greater than the potential at b. During the motion tl1e oniy force acting on the object is the electric force.
