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 seperated 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 descibng the motion of the cart as you can
