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.

One charge is decreased to one-third of its original value, and a second charge is decreased to one-half of its original value. how will the electrical force between the charges compare with the original force? a- it will increase to six times the original force. b- it will increase to thirty-six times the original force. c- it will decrease to one-sixth the original force. d- it will decrease to one-thirty-sixth the original force.
