Draw the net electric field at the center of: A line segment of length 1.0 m with a +1-C charge and a –1-C charge at its endpoints;

An equilateral triangle of side length 1.0 m with alternating +1-C, –1-C, and +1-C charges placed at its vertices;

A square of side length 1.0 m with alternating +1-C, –1-C, +1-C, and –1-C charges placed at its vertices

Calculate the magnitude and determine the direction of the net electric field at the center of each of the above configurations.​

Since you have not included the experiment situation and the data, of course, i can not give you specific details about it. but i can you with this question.1) i will assume that the motion is projectile (parabolic) motion.2) yes, the horizontal distance depends on the horizontal velocity as, naming vx the horizontal velocity and t the time, it is: x = vx × t3) now, observe that the flight time depends on the vertical velocity as, naming voy the initial vertical velocity, t the time and y the vertical distance before reaching the ground: y = yo + voy×t - gt² / 2.the higher the initial vertical velocity (voy) the longer the object will be flying and so t will be higher in the equation for the horizontal distance.that explains the relationship between the horizontal distance and the horizontal velocity.
