Physics Please help me solve E3B9. Thanks E3B.8 Consider a region of space where the electric field is everywhere equal to E = [-400, +300, 0] N/C. y -10 cm E B C We'd like to calculate the potential difference - A between points A and B. We will do this by dividing the straight-line path going from A to B into 20 equal steps, which we will consider to be "sufficiently small" steps. (a) List the components of dr for each step. (b) Argue that Ē. dr has the same value for each step and compute that value. (Hint: Use the component expres- sion for the dot product.) (c) Calculate the value of fĒ. dr in this case. (d) Calculate the potential difference PB - PA. If the poten- tial at A is -5 V, what is the potential at B? (e) In this particular case, show that SẼ • dr = Ē. Ar, where Ar is the entire displacement from A to B? What would have to be different about the electric field to make fĒ. dr #Ē. A7? E3B.9 Consider the situation described in problem E3B.8. Repeat all of the parts of that problem for the path from B to C instead of A to B. (That is, in the statement of that problem, replace "A" by "B" and "B" by "C" everywhere.)
