A charged ball is fired straight up, starting from a point at which the electric potential is +200 V. The equipotentials are equally spaced, as shown in the picture above, with successive lines in the picture being exactly 1.00 meter apart. This is done at the surface of the Earth, where the gravitational field has a value of g = 10.0 m/s2, directed straight down. The magnitude of the charge on the ball is 10 millicoulombs The ball has a mass of 200 grams. If the ball has a negative charge instead, what initial velocity must it have at the +200-V level for it to reach its maximum height at the +700-V level? _______ m/s
