A3500-kg statue is placed on top of a cylindrical concrete (y = 2.3 times 10^10 n/m^2) stand. the stand has a cross-sectional area of 7.3 times 10^-2 m^2 and a height of 1.8m. by how much the statue compress the stand?

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.
