An initially neutral rubber rod is rubbed with fur, so that the fur becomes positive. The rod then briefly touches an uncharged electroscope and the leaves of the electroscope separate and stay separated even after the rod is removed. Finally, a second rod with an unknown charge comes near the electroscope without touching it and the leaves of the electroscope move farther apart. What is the charge of the second rod?

an initially neutral plastic pipe is rubbed with an initially neutral cloth. Both objects are now charged, and it is shown that the pipe is negatively charged. Explain both answers. a) Describe the charge state of the cloth. b) Would the total charge of the pipe and the cloth (added together) be positive, negative or zero?

Two hard rubber spheres, each of mass m = 16.0 g, are rubbed with fur on a dry day and are then suspended with two insulating strings of length L = 4.70 cm whose support points are a distance d = 3.24 cm from each other as shown in the figure below. During the rubbing process, one sphere receives exactly twice the charge of the other. They are observed to hang at equilibrium, each at an angle of θ =...

What happens when a charged glass rod (positive charge when rubbed with balloon) is first held near a neutral pith ball, and then touches the ball? Do the rod and the ball repel or attract each other after?

True or false. 1. When a neutral glass rod is rubbed with a neutral silk cloth, the rod acquires a positive charge as the cloth acquires a negative charge as protons are transferred from the cloth to the rod 2. When an electron is taken from point A to point B along an electric field line that points from B to A, the electric potential energy of the system decreases 3. When a point charge is moved from point A...

if a positively charged glass rod is touching the metal ball in an initially neutral electroscope, what charge will generate in the LEAVES of the electroscope through conduction? Please draw the conducting parts of the electroscope and show the distribution of charges?? (include the charges in the leaves and ball after the glass rod touches it and explain how and why that charge was acquired?)

a positively charged rod is brought near a face of initially neutral metal ball, the other face of the ball is connecting to the earth by wire . After cutting the wire connecting the ball to the earth , what will be the interaction between the rod and the metal ball? A. they attract each other . b. not enough information . c. they repel each other . d. there is no interaction between them

This problem explores the behavior of charge on realistic (i.e. non-ideal) insulators. We take as an example a long insulating rod suspended by insulating wires. Assume that the rod is initially electrically neutral. For convenience, we will refer to the left end of the rod as end A, and the right end of the rod as end B (Figure 1). In the answer options for this problem, "weakly attracted/repelled" means "attracted/repelled with a force of magnitude similar to that which...

Suppose an object has a charge of 1 C and gains 1.19 ✕ 1019 electrons. (a) What will be the net charge (in C) of the object? (b) If the object has gained electrons from a neutral object, what will be the charge (in C) on the neutral object? (c) Find and explain the relationship between the total charges of the two objects before and after the transfer. A) The total charge before and after will be equal to 1...

Suppose the two cars had rubber bumpers in the front and back – similar to the bumper cars children (of all ages!) ride at amusement parks. Also, suppose that the cars are sturdy enough that the metal they are made of does not bend during the collision. In this case, the cars would undergo a perfectly elastic collision. Assume just like in the first collision question that the SUV (initially moving to the right) collides into the stationary smart car....
