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, 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. Part (a) In what direction is the electric field in this situation? Select the correct answer a. Left b. Right c. It's directed horizontally, but we can't tell whether it is left or right. Up d. Up e. Down f. It's directed vertically, but we can't tell whether it is up or down. g. The direction of the field depends on whether the ball has a positive charge or a negative charge.
