1. How does the fundamental resonant frequency of a stretched string change if the tension in the string is doubled

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.)

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
