Question: Space scientists have a large test chamber from which all the air can be evacuated and in which they can create a horizontal uniform electric

Space scientists have a large test chamber from which all the air can be evacuated and in which they can create a horizontal uniform electric field. The electric field exerts a constant horizontal force on a charged object. A 15 g charged projectile is launched with a speed of 6.0 m/s at an angle 35° above the horizontal. It lands 2.9 m in front of the launcher. What is the magnitude of the electric force on the projectile?
