The figure shows four orientations of an electric dipole in an external field. For each of the four dipoles, give the angle between the p vector (dipole moment) and the E vector (electric field vector) that is used in the formula for torque: torque = p E sin (phi) where phi is the angle between the p and E vectors. For example, how do you know if you use theta or 180 - theta for orientation (1); do you use theta or negative theta for orientation 4?
A water molecule with any spatial orientation is placed nearby a spherical distribution of charges Q. Describe the dynamic behavior (rotation and translation) of the water molecule.
Suppose a van e Graff generator builds a negative static charge and grounded conductor is placed near enough to it so that a 7.0 x 10^6 coulombs of negative charge arcs to the conductor. Can you help me to conceptualize the steps in calculating the number of electrons that are transferred?
