Current Attempt in Progress An Electrostatic Positioner. You and your team are designing a device that can be used to position a small, plastic object in the region between the plates of a parallel-plate capacitor. A small plastic sphere of mass m = 1.10 × 10-2 kg carries a charge q = +0.190 μC and hangs vertically (along the y direction) from a massless, insulating thread (length/ = 10.0 cm) between two vertical capacitor plates. When there is no electric field, the object resides at the midpoint between the plates (at x = 0). However, when there is a field between plates (in the +x direction) the object moves to a new equilibrium position. (a) To what value should you set the field if you want the object to be located at x = 2.10 cm? (b) To what value should you set the field if you want the object to be located at x = -3.15 cm? (a) Number i Units (b) Number i Units

Two identical spheres are attached to silk threads of length L=0.60 m and hung from a common point as shown in the figure. Each sphere has a mass m=7.0 g. One sphere is given a charge q1, and the other is given a different charge q2, this causes the spheres to separate so that when the spheres are in equilibrium, each thread makes an angle = 20 degrees with the vertical. A small wire is then connected to the spheres, allowing charge to be transferred from one sphere to the other until the two spheres have equal charges, the wire is then removed. Each thread now makes an angle = 30 degrees. Determine the original charge (in micro-coulomb) of q1.
An electron is traveling at {v} × 106 m/s when it enters an electric field that slows it down. The field has a strength of 6372 N/C. How far does the electron penetrate the field before it stops?
A small plastic ball with a mass of 6.65 10-3 kg and with a charge of +0.149 µC is suspended from an insulating thread and hangs between the plates of a capacitor (see the drawing). The ball is in equilibrium, with the thread making an angle of 30.0° with respect to the vertical. The area of each plate is 0.0138 m2. What is the magnitude of the charge on each plate? C

A thin metal ring of radius R is placed horizontally and charged with charge Q. A point like object with mass m and charge q is let fall vertically from a height H measured from the plane of the ring. The initial velocity is zero. The object is falling along the axis of a ring. What is the velocity of the object, when it reaches the middle of the ring? Gravitational acceleration is denoted by g.
