Suppose that a pair of large parallel plates are separated by a distance d = .4 m and have a potential difference of AV = 2000 V between them. A small cart with charge q = +1.4.10⁻⁵ C and mass m = .3 kg is placed near one of the plates. If the ground has a coefficient of friction of µₖ = 13, what is the speed of the cart when it slides into the other plate?
