An infinite sheet of charge is located in the y-z plane at x = 0 and has uniform charge denisity σ1 = 0.25 μC/m2. Another infinite sheet of charge with uniform charge density σ2 = -0.42 μC/m2 is located at x = c = 36 cm.. An uncharged infinite conducting slab is placed halfway in between these sheets ( i. e., between x = 16 cm and x = 20 cm). 1)What is Ex(P), the x-component of the electric field at point P, located at (x, y) = (8 cm, 0)?

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?
