A stationary block has a charge of +6.0*1^-8C. A 0.80-kg cart with a charge of +4.0*106-8C is initially at rest and separated from the block by 0.4m. The cart is released and moves along a frictionless surface to a distance of 1.0m from the block. Determine as many values of the physical quantities describng the motion of the cart as you can

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.
