Two conducting spheres, each with charge Q, repel each other. The spheres are attached to very light and long strings and are hung from the same point. The spheres have a mass of 0.2g and are separated by 5 cm, when measured from center to center. The string tension force is measured to be 0.002 N, what is the charge on one of the sphere? (Hint: draw a diagram of the string tension force, the gravitational force, and the electrostatic...

Suppose I have two conducting balls each of 10-6 coulombs of charge separated by 2 meters. A neutral wand of equal area to each ball touches one of the balls and allows charge to transfer. Then the wand is separated from the first ball and brought into contact with the other ball. After the charge is allowed to transfer, the wand is removed from the system. Determine the net force between the two conducting balls after the wand is removed.

Question 1: You measured the force between two charged pith
balls where the pith balls were of the same size and mass. Your
assumption was that the charge on the balls was the same.
Consider this change to that situation. Instead of identical
pith balls, one has twice the charge of the other. Both pith balls
hang from strings of length L. Assume the masses are the same and
both pith balls hang at the same angle. Derive...

2. (a) Two small metallic spheres, each of mass 2.00 g, are suspended as pendulums by light, non-conducting strings as shown below. The spheres are given the same electric charge, and it is found that they come to equilibrium when each string is at an angle of 30° with respect to the vertical. (a) If the strings are each 10.0 cm long, what is the magnitude of the charge on each sphere? Assume that the gravitational force between the two...

Two small metallic spheres, each of mass 2.00 g, are suspended as pendulums by light, non-conducting strings with lengths of 10 cm. The spheres are given the same electric charge, and it is found that they come to equilibrium when each string is at an angle of 30 degrees with respect to the vertical. 1) What would happen if the charges on the two spheres were not equal? Would it be possible for the two spheres to hang symmetrically at...

1. Suppose that for these two equally charged pith-balls of mass m 1.0 × 10-4kg hanging from strings of length a-0.25m, θ 10°-π/18rad, what charge q is on each of them? 2. A positive ion of charge q1.6x 10-1C and mass 1.6x 10-23kg is "shot" at initial speed vo 5000m/s into a region containing a strong electric field E = 1000N/CJ of width L = 0.2m used to deflect a beam of such ions.

1. Two equal point charges of +2.85×10−6 are placed 0.215 m a part (Part A) What are the magnitude of the force each charge exerts on the other? 2. Two small spheres spaced 50.0 cm apart have equal charge. (Part A) How many excess electrons must be present on each sphere if the magnitude of the force of repulsion between them is 5.21×10−21 N ?

Question 7 - Rank by force Three balls, with masses of 4m, 2m, and m, are equally spaced along a line. The spacing between neighboring balls is r. We can arrange the balls in three different ways, as shown in the figure. In each case, the balls are in an isolated region of space very far from anything else. 2m 4m 4m 2m Question A T> >3 1>2=3 1>3>2 2>1>3 2>1=3 2>3>1 3>1>2 3>1=2 3>2>1 All equal 2m...

Question 1 1 out of 1 points Two small metallic spheres of mass 0.2g are suspended as pendulums by light strings of length L. The spheres are given the same electric charge so they repel each other. They come to equilibrium when each string is at an angle of 5 degrees from vertical. There are three forces: tension, weight, and electric force. Find the electric force required for equilibrium. Do this like a Physics 251 problem. Selected Answer: 000172 Question...
