So my professor is asking us for the electric potential energy formula and the electric kinetic energy formula. He gives us two equations and asks if each equation is correct. I pretty sure that the potential energy one is correct, but I can't find the Kinetic energy equation.

PE=(Ke*(q1*q2))/r

KE=(Ke*(q1*q2))/r^2

Are these equations correct?
If not, what are the correct equations?

In the Electric Potential Laboratory experiment, what does mean the letter A?, in this formula. V(r)=A ln(r/ra) Better to ask what is the name of each term in this formula? This is my Question to answer [[[Use the above to establish a value for the constant A. What units should it have?]]]] But I do not know HOW TO FIND V(r), in this formula, we measure 3 V------>, [V1 , V2 , V3] and we measured r, and we calculated...

I had to make a calibration curve for the bradford dye-binding assay. My professor wanted us to fit the data to three different mathematical functions: a straight line in the form of y=mx+b, a second-order polynomial: y=a.x2+b*x+c a rectangular hyperbola on the form:y=(a*x)/(b+x) my results (I used the SciDavis program): y=0.0526X+0.0353 y=0.00987+0.063X-0.000537x2 y=(5.07X)/(76.3+x) I am supposed to use the graph i made to estimate the concentration of protein in my bacterial extract.

Each alpha particle in a beam of alpha particles has a kinetic energy of 5.0 MeV. Through what potential difference would you have to accelerate these alpha particles in order that they would have enough energy so that if one is fired head-on at a gold nucleus it could reach a point 1.0x10^-14 m from the center of the nucleus? I know that the answer is delta V = 9e6 Volts I am struggling to get past KEi = 5.0...
