Acharge moves from point a to point b in an electric field. what is true in general about the energy of the charge?

a. the sum of the potential energy and the kinetic energy at a is the same as that at b.

b. the sum of the potential energy and the kinetic energy at a is greater than that at b.

c. the sum of the potential energy and the kinetic energy at a is less than that at b.

d. the sum of the potential energy and the kinetic energy at b fluctuates.

Calculate the minimum energy required to remove one proton from the nucleus 126c. this is called the proton-removal energy. (hint: find the difference between the mass of a 126c nucleus and the mass of a proton plus the mass of the nucleus formed when a proton is removed from 126c.) express your answer with the appropriate units. emin e m i n = nothing nothing request answer part b how does the proton-removal energy for 126c compare to the binding energy per nucleon for 126c, calculated using eb=(zmh+nmn−azm)c2?
