The direction of a moving object will not change if the net force acting on it is

The direction of a moving object will not change if the net force acting on it is zero.

Explanation:

If there is a net force acting on a body, the body may accelerate, slow down, or change direction. In other words, an unbalanced net force may change the state of motion of a body.

The only way a moving object will not change its direction if the body is moving with a constant velocity, meaning all the forces acting on the body are in equilibrium (or balanced). In other words, the net force acting on it is zero, and the speed, as well as direction, would not change.

Therefore, we conclude that the direction of a moving object will not change if the net force acting on it is zero.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
