Apositive charge q is placed at the origin. four other positive charges are placed on a circle in the x-y plane centered on q as shown. the top charge is located on the y axis and has a magnitude of 3q. the three bottom charges are symmetric about the y axis as shown and each has magnitude q.
1) which of the following statements best describes fx, the x component of the net force on the charge at the origin
fx > 0
fx = 0
fx < 0
3) for the collection of charges shown in the above problem, which of the following statements best describes fy, the y component of the net force on the charge at the origin
fy > 0
fy = 0
fy < 0

1. FX = 0 since the bottom charges are symmetrical about the y axis and the top charge is aligned with the y-axis
3. FY > 0 since the bottom charges do not equate the top charge. The bottom charges have horizontal components which is less than q and adding them all, will not result to 3q.

The answer would be a) -80of

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.
