- QUESTION 11 Redo Example 18.1 (p. 773, "How strong is the Coulomb force relative to the gravitational force?") for two electrons situated 53 pm apart. Express your answer asnx 1042 and type in just the value of n with two significant figures.4) Just as in problem 3 above, a neutral molecule has a dipole moment of 5 Debyes (1.6E-29 Cm) pointing in the x direction. It can be modeled as two charges +e and -e separated from one another by 1E-10 meters (1 angstrom), straddling the origin along the x axis, at x=0. An electron is located on the y axis at y=10 angstroms. What is the force (both magnitude and direction) on the electron by the dipole? ie (o, 10Å) --> X e cx=0.5Å,yr0)Two point charges of mass m each are suspended in the gravitational field of the Earth by two non-conducting massless strings, each of length 1, attached to the same fixed point.
