A spring with an unstrained length of 0.074 m and a spring constant of 2.4 N/m hangs vertically downward from the ceiling. A uniform electric field directed vertically upward fills the region containing the spring. A sphere with a mass of 5.1 × 10³ kg and a net charge of +6.6 µC is attached to the lower end of the spring. The spring is released slowly, until it reaches equilibrium. The equilibrium length of the spring is 0.059 m. (a) Draw the free-body diagram showing the forces that act on the sphere. (b) What is the magnitude of the external electric field?

An outside force, Fo, brings two small metal spheres, A and B, at rest from a long distance away to a point where they are 0.9 meters apart. They are then connected by a non-conducting string of negligible mass. The spheres have mass mA = 5.2 g and mB = 10.4 g and both have equal positive charges of 5 μC. (You may assume the length of the string is much greater than the radii of the spheres.) 1)What was the total work done by the outside force to bring the spheres to the point described? 2)What was the total work done by the electric field when the two sphere were brought together as described? 3)What is the potential energy of the two sphere system after they have been brought together as described? (You may assume the spheres had zero potential energy when they were a long distance apart.) 4)Suppose you cut the string. At that instant, what is the magnitude of the acceleration of sphere A? 5)After a very long time, what is the magnitude of the velocity of sphere A?

A horizontal electron beam consists of electrons moving at 2000 m/s through two parallel, horizontal plates that are 0.01 m long and generate a uniform and constant 0.5 N/C electric field that points upward.

A small object is connected to a lightweight cord of length L=1.20 m that is tied to a point P, as shown in the figure. The object, string, and point all lie on a frictionless, horizontal table. The object has mass m=.0100kg and charge q= 2.10 uC and is released from rest when the string makes an angle theta=60 with a uniform electric field of magnitude E=260 V/m. Determine the speed in m/a of the object when the string is parallel to the electric field.
Two identical balls each having a density p are suspended from a common point by two insulating strings of equal length. Both the balls have equal mass and charge. In equilibrium, each string makes an angle with the vertical. Now, both the balls are immersed in a liquid. As a result, the angle does not change. The density of liquid is o. Find the dielectric constant of the liquid.
