a ball with mass m travels at a speed v. It collides head-on and inelastically with an identical ball that is initially at rest and sticks to it. What percentage of the original kinetic energy is lost in the collision

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.)

what are the options.

explanation:

probably not the "magnets"in the magnet, so to speak, are thought to be electrons orbiting in shells. vurrent loops two sides to the loop
