I have tried the equation Va - Vb = -Wba/q, where Va is the potential at point A and Vb is the potential at point B. This equation was from a textbook, however, I later realized that it was only going to find the work done to move the object from point B to point A. Since the problem gives me...
A total of eight tiny conducting spheres, each carrying a charge of -110 nC, are placed one each at the corners of a cube 1.2 m on a side. Find the potential at the center (in V).
What is the electric field at the center (in N/C)?
A 2.00 mm diameter conducting sphere in vacuum is charged with +28.0 nC. Determine the potential at a distance of 1.70 m from its center. [Hint: Since 1.70 m >> 2.00 mm this is essentially a point-charge.]
We wish to place a small charged sphere at a distance of 5.0 m from a point in space such that the voltage at that point is 1.20 V. How much charge should be on the sphere (in nC)?
There is an E-field in a region of space, and a +55.0 nC charge is placed at a point where the potential is 535 V. When released the charge moves, while the field does 210.0 µJ of work on it. What is the potential of the final location of the charge?
A person pushes a 18.0 kg lawn mower at constant speed with a force of 71.0 N directed along the handle, which is at an angle of = 43.0° to the horizontal .
(a) Draw the free-body diagram showing all forces acting on the mower. (Do this on paper. Your instructor may ask you to turn in this...
