What is the magnitude of the electric field at the point on the x-axis, between the charges, where the electric potential is zero?
Determine the rate of entropy generation (i.e. irreversibility) assuming the ambient temperature is 70 °F. You may neglect the combustion products (exhaust) in your analysis. Your result should be in units of Btu/hr-°R
