Problem 2. (max. 20 = 10+10 points) (a) You are asked to determine the path that requires the least work for a force field F to move a particle from one point to another. You first do a quick calculation and determine that F is conservative. How would you reply to the request? (b) You are in a physics lab, in the presence of a force field G. You do an experiment and measure that the amount of work required for G to move an object along a path C1 from point Po to point P1 is 2 Joules, while the amount of work required to move the same object along another path C2 from Po to Pi is 5 Joules. Your physics instructor tells you that G is the electric force between two charges. Should you believe your physics instructor? Justify your
