PLEASE HELP how does the total horizontal distance traveled by the projectile change as the launch angle is increased from 30 degrees to 45 degrees above the horizontal? (assume the same initial speed, Vi)

Atriangle with equal sides of length 10 cm has -2.5-nc charged objects at each corner. part a determine the direction of the electrical force exerted on the object at the top corner due to the two objects at the horizontal base of the triangle. determine the direction of the electrical force exerted on the object at the top corner due to the two objects at the horizontal base of the triangle. horizontally rightward vertically downward vertically upward horizontally leftward
