In the figure, charge q2 experiences no net electric force. What is  q1 ? Express your answer in nanocoulombs

A charge Q is to be apportioned between two small conducting spheres. How much of this charge must be placed on each sphere in order to result in the maximum force between the spheres? Hint: Sketch a plot of the magnitude of the force vs the amount of charge on one sphere. What shape is the plot? Where is the peak for such a curve?

Two small balls, each of mass 5.5 g, are attached to silk threads 40 cm long, which are in turn tied to the same point on the ceiling, as shown below. When the balls are given the same charge Q, the threads hang at 5.0° to the vertical, as shown below. What is the magnitude of Q? How do the signs of the two charges compare? Hint 5.0° Q The magnitude of Qis charge. Question Help: Message instructor Submit Question μC, and the two charges carry Select an answer sign of

A plastic balloon that has been rubbed with wool will stick to a wall.a. Can you conclude that the wall is charged? If not, why not? If so, where does the charge come from?b. Draw a charge diagram showing how the balloon is held to the wall.

The figure below shows the electric field lines for two point charges separated by a small distance. (a) What are the signs of q1 and q2? (b) Determine the ratio q1/q2. Express your answer to 3 significant figures.

Red blood cells can often be charged. Consider two red blood cells with the following charges: -17.6 pc and +49.8 pC. The red blood cells are 3.31 cm apart. (1 pC = 1 × 10-12 C.) ..(a)..What.is.the magnitude of the force on each red blood cell? Enter a number. alculate the force of a charged particle on another charged particle? N Are the red blood cells attracted or repulsed by each other? attracted repulsed (b) The red blood cells come into contact with each other and then are separated by 3.31 cm. What magnitude of force does each of the red blood cells now experience? What is the net charge of the system? Assuming the cells are identical, how much charge will each have after contact? N Are the red blood cells attracted or repulsed by each other? attracted repulsed

A 0.024 g plastic bead hangs from a lightweight thread. Another bead is fixed in position beneath the point where the thread is tied. If both beads have charge qq, the moveable bead swings out to the position shown in (Figure 1).   Figure 1 of 1   Part A What is q?

Two point charges, +3 C and -6 C, are separated by 2.0 m. They are NOT free to move. What is the magnitude of the electrostatic (Coulomb) force between the charges?

This is IB Physics, so I would need to have the units IB uses for Physics. Question is on the picture.

In class this week we used the following expression a lot: dĒ = _¹ da. Which of Απεο 2 the following best characterizes what this actually is? This is the differential contribution to the electric field at some point in space due to the differential charge element, dq, as given by Coulomb's law. This is the energy stored in a differential piece of the electric field. This is rate at which the electric field is changing in space as charge changes. This is the contribution to the electric field due to one electron or proton in the charged object. None of the others is a valid explanation of the expression
