Two guys who weigh the same are holding onto a massless pole while standing on horizontal frictionless ice. The guy on the left is at -3 m and the guy on the right is at +3 m. If the guy on the left starts to pull on the pole, where do they meet?a. -3 mb. 0 mc. +3 m

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
