- Is it possible to charge an insulator such as a glass or a rubber? Explain.I have a piece of PVC that keeps attracting particles to it like dust, hair, etc. (seemingly to be statically charged to the PVC). Please explain the process of why it is happening and provide sources for the information used to answer the question.1. You have a rigid electric dipole. You place it into an uniform electric field. Doubling the field's strength will have which of these effects? Assume the dipole moment initial is oriented at a 45° angle with respect to the field. (Select all which apply) ESOS Stedmed a) Torque doubles b) Torque halves c) Energy doubles d) Energy halves e) none of these
- 104) 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)4.) Figure Q.2 (b) shows a cylindrical structure with length of 50 m. The inner and the outer surface are separated by free space and located at r = a and r = b respectively. The inner and outer surface of the structure contain a total charge of +1pC and -1pC, respectively. An infinitely long line charge with line charge density of +1pC/m is introduced along the axis of the structure. Given that a = 1 mm and b = 2 mm. +pa C/m? -Рь С/m? Figure Q.2(b) i. Calculate +pa and -pp at radius a and b respectively ii. Find D and E in all regions iii. Sketch graph |D| versus r
