Suppose that a meter stick is supported at the center , and a 40-N block is hung at the 80-cm mark . Another block of unknown weight just balances the system when it is hung at the 10-cm mark. What is the weight of the second block? (photo attached above)​

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.)
