PRS01 Physics Experience Have you taken a class in Electricity & Magnetism before? 1. No, never 2. Yes, here (8.02) 3. Yes, here (8.02 TEAL) 4. Yes, other college 5. Yes, high school (regular) 6. Yes, high school (AP)PRS01 Math Background What is the highest level of mathematics you have credit for? Please choose only one option below. 1. Credit for 18.01 in any form 2. Halfway through 18.02a (finishing this spring) 3. Credit for 18.02 in any form 4. Credit for 18.03 in any form 5. Beyond 18.03PRS01 Math Background Are you familiar with these concepts from vector calculus? 1. I’ve never seen them before, and I am not so comfortable with math 2. I’ve never seen them before, but I pick up new math concepts quickly 3. I’ve seen them before, but definitely need some review 4. I am comfortable with vector calculusPRS01 The field line above corresponds to the vector field: 1. ˆˆ(, ) sin()xy x=+FiGjjjj2. ˆˆ(, ) sin()xy x=+FiG3. ˆˆ(, ) cos()xy x=+FiG4. ˆˆ(, ) cos()xy x=+FiG5. I don’t knowPRS01 The above vector field is created by: 1. Two sources (equal strength) 2. Two sources (top stronger) 3. Two sources (bottom stronger) 4. Source & Sink (equal strength) 5. Source & Sink (top stronger) 6. Source & Sink (bottom stronger) 7. I don’t knowPRS01 Here there is an initial downward flow. 1. The point is a source 2. The point is a sink 3. I don’t knowPRS01 These two circulations are in: 1. The same direction (e.g. both clockwise) 2. Opposite directions (e.g. one clockwise, one ccw) 3. I don’t knowPRS01 The “grass seeds” field plot above is a representation of the vector field: 22ˆˆ1. ( , )xy x y=+FiGj 22ˆˆ2. ( , )xyyx=+FijG ˆˆ3. ( , ) sin( ) cos( )xyxy=+FijG ˆˆ4. ( , ) cos( ) sin( )xyxy=+FijG 5. NOT SUREPRS01 Two opposite charges are placed on a line as shown below. The charge on the right is three times larger than the charge on the left. Other than at infinity, where is the electric field zero? qL qR 1. Between the two charges 2. To the right of the charge on the right 3. To the left of the charge on the left 4. The electric field is nowhere zero 5. Not enough information – need to know which charge is
