(a) Determine the work done on a fluid that expands fromi to f as indicated in Figure.
(b) How much work is done on the fluid if it is compressedfrom f to i along the same path? ## Answers (1) 2021-04-17
Work done ON the fluid is determined by taking negative ofthe area under given curve from Point (i) to Point (f):
Work Done ONFluid For (i) ---> (f)} = -{Area Under Curve} =
$$\displaystyle=-{\left({6.0}{e}+{6}\right)}\cdot{\left({1}\right)}\pm{\left({\frac{{{1}}}{{{2}}}}\right)}\cdot{\left({6.0}{e}+{6}+{2.0}{e}+{6}\right)}\cdot{\left({1}\right)}\pm{\left({2.0}{e}+{6}\right)}\cdot{\left({1}\right)}$$
$$\displaystyle=-{1.20}{e}+{7}$$ Joules
Work done ON fluid during reverse compression along same pathfrom Point (f) to Point (i) will be equal to the negative of above Item(a) result:
{Work Done ON Fluid For (f) --->(i)} = 1.20e+7 Joules

Assume that a ball of charged particles has a uniformly distributednegative charge density except for a narrow radial tunnel throughits center, from the surface on one side to the surface on the opposite side. Also assume that we can position a proton any where along the tunnel or outside the ball. Let $$\displaystyle{F}_{{R}}$$ be the magnitude of the electrostatic force on the proton when it islocated at the ball's surface, at radius R.
