Get started for freeQuestion: Three charges are at the corners of an equilateral triangle (side l) as shown in Fig. 17–45. Determine the potential at the midpoint of each of the sides. Let \[{\bf{V = 0}}\] at \[{\bf{r = }}\infty \].
FIGURE 17–45 Problem 75.
(I) An electron and a proton are \({\bf{0}}{\bf{.53 \times 1}}{{\bf{0}}^{{\bf{ - 10}}}}\;{\bf{m}}\) apart. What is their dipole moment if they are at rest?
When the proton and electron in MisConceptual Question 6 strike the opposite plate, which one has more kinetic energy?
(a) The proton.
(b) The electron.
(c) Both acquire the same kinetic energy.
(d) Neither—there is no change in kinetic energy.
(e) They both acquire the same kinetic energy but with opposite signs.
(II) Two point charges, \({\bf{3}}{\bf{.0}}\;{\bf{\mu C}}\) and \({\bf{ - 2}}{\bf{.0}}\;{\bf{\mu C}}\) are placed 4.0 cm apart on the x axis. At what points along the x axis is (a) the electric field zero and (b) the potential zero?
Question: (I) 650 V is applied to a 2800-pF capacitor. How much energy is stored?
