Get started for freeShow that an infinite line of charge with linear charge density exerts an attractive force on an electric dipole with magnitude . Assume that, the distance from the line, is much larger than the charge separation in the dipole.
An electric dipole is formed from charges spaced apart. The dipole is at the origin, oriented along the -axis. What is the electric field strength at the points (a) and
What are the strength and direction of the electric field at the position indicated by the dot in FIGURE ? Specify the direction as an angle above or below horizontal
Twodiameter charged disks face each other, apart. The left disk is charged to and the right disk is charged to.
a. What is the electric field, both magnitude and direction, at the midpoint between the two disks?
b. What is the forceon acharge placed at the midpoint?
A small object is released at point in the center of the capacitor in FIGURE . For each situation, does the object move to the right, to the left, or remain in place? If it moves, does it accelerate or move at constant speed?
a. A positive object is released from rest.
b. A neutral but polarizable object is released from rest.
c. A negative object is released from rest.
