Find the minimum force to pop a balloon given that the pressure needed to do the job is 2.5* 10^(-7) N/m^2 for the following two instruments: your finger and a pin. A finger has area 1.0* 10^(-4) m^2 and a pin has area 2.5* 10^(-7) m^2.

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.)
