Three point charges with values q1 = 8.00 nC , q2 = 3.00 nC , and q3 = 7.00 nC are placed on three consecutive corners of a square whose side measures s = 3.00 m . Point A lies at the fourth corner of the square, diagonally across from q2. Point B lies at the center of the square. What are the values of the electric potential at point A and at point B? How much energy (supplied as work) is required to move a test charge q4 = 2.00 nC from point A to point B? Assume the zero of electric potential is chosen to be.

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
