The climber dropped her compass at the end of her 240-meter climb. how long did it take to strike bottom?

240 = 0+1/2 (-9.8t

240 = -4.9t

240/-4.9 = t
49.0 = t

t= 7.0s

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.)
