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 5.00 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.1. What is the electric potential at point a due to q1 and q2 ?2. What is the electric potential at point b ?A point charge q3 = -6.00 μC moves from point a to point b . How much work is done on q3 by the electric forces exerted by q1 and q2 ?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?
