Please help. 10 is the main question but 11&12 are a part of the same question so I need help solving all three.

2 points In the drawing below, E = 4.ON/C and d = 1.5m. Calculate the work done by the electric field in moving a 5.0*10"-9C charge from A to B. Be sure to include - sign if your answer is negative. (The direction of travel is at 30.0degrees to the field) Your answer needs to be in J but you don't need to enter the unit in your answer for this question. Note: the answer for this question may be very large or very small so using scientific notation will help. This system is very particular about entering numbers in scientific notation, for example to enter 3.1x10-24 you must type 3.1*10^-24 in the answer box exactly in this format with no spaces. For this question you MUST use one place after the decimal, as in the formatting example above. CO TOU 30 A Type your answer.. 2 points In the situation in diagram (c) above, calculate the potential energy difference between the 5.0*10^-9C charge at point B and at point A in an.
