A helium nucleus is composed of two protons (positively charged) and two neutrons (charge neutral). The distance between the two protons in the nucleus is 5.18E-15 m. What is the electric force between the two protons (in Newtons; use positive sign for repulsive forces and negative sign for attractive forces)

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
