Question 1 A proton and an electron are released from rest in the centre of a capacitor. How does the acceleration of the proton, ap, compare with the acceleration of the electron, ae? 0 ap = ae 0 ap ae Question 2 Two charged, square plates, separated by a distance of 29.3 cm and each with a side length of 36.6 cm, make up a parallel-plate capacitor. The electric eld inside the plates is 1.70403 N/C. If the separation distance is halved, what would the electric eld inside the plates become? 0 1.70E+03 N/C O 850. me O 425 me O 3.40E+03 N/C Question 3 + + p g p + 5 . + .. , .. t 2 3 4 + o- o- o - + + p y .- + 0 1 + . . - + In the figure above, a positive object at position 5 is let go from rest.
