Suppose a ship travels along the Saint Lawrence Seaway connecting the Atlantic Ocean with Lake Ontario. Will the ship float lower, higher, or at the same height in Lake Ontario as it does in the Atlantic Ocean? Explain.

260 miles per hour

explanation:

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.)
