Acharge q1 = 5 μc is at the origin. a second charge q2 = -3 μc is on the x-axis, 0.8 m from the origin. the electric field at a point on the y-axis, 0.5 m from the origin is: a. 1.66 x 105 n/c, 810 below the positive x-axis b. 1.66 x 105 n/c, 810 above the positive x-axis c. 1.66 x 105 n/c, 810 below the negative x-axis d. 1.66 x 105 n/c, 810 above the negative x-axis

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?
