A snowball hits a window with a force of 200 N. According to Newton's 3rd Law, what must be the force of the window on the snowball?

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.)

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

tbh i don't know the answer for this question
