Using the circuit schematic in the image below, describe the bulb T? Assume the all lamps
have the same resistance.
T is equally bright as U and V (all on)
T would be brighter if U was unscrewed
T is dimmer than U and V (all are on)
T is brighter than U and V (all are on)

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.
