Question

Figure 21-18 shows four situations in which particles of charge +q or -q are fixed in place. In each situation, the particles on the x axis are equidistant from the y axis. First, consider the middle particle in situation 1; the middle particle experiences an electrostatic force from each of the other two particles. (a) Are the magnitudes F of those forces the same or different? (b) Is the magnitude of the net force on the middle particle equal to, greater than, or less than 2F? (c) Do the x components of the two forces add or cancel? (d) Do their y components add or cancel? (e) Is the direction of the net force on the middle particle that of the canceling components or the adding components? (f) What is the direction of that net force? Now consider the remaining situations: What is the direction of the net force on the middle particle in (g) situation 2, (h) situation 3, and (i) situation 4? (In each situation, consider the symmetry of the charge distribution and determine the canceling components and the adding components.) I need to show all work

x axis are equidistant from the y axis. First, consider the middle
particle in situation 1; the middle particle experiences an electro-
static force from each of the other two particles. (a) Are the magni-
tudes F of those forces the same or different? (b) Is the magnitude
of the net force on the middle particle equal to, greater than, or less
than 2F? (c) Do the x components of the two forces add or cancel?
(d) Do their y components add or cancel? (e) Is the direction of the
net force on the middle particle that of the canceling components or
the adding components? (f) What is the direction of that net force?
Now consider the remaining situations: What is the direction of the
net force on the middle particle in (g) situation 2, (h) situation 3,
and (i) situation 4? (In each situation, consider the symmetry of the
charge distribution and determine the canceling components and
the adding components.)
