An electric dipole consists of two point charges, q1 = + 12 nC and q2 = -12nC, placed 10 cm apart. Compute the potential at point (a).

An isolated charged soap bubble of radius Ro = 4.65 cm is at a potential of V= 283.0 volts. If the bubble shrinks to a ridios that is 39.0% of the initial radius, by how much does its electrostatic potential energy U change? Assume that the charge on the bubble is spread evenly over the surface, and that the total charge on the bubble remains constant. AU = Upd- Unl = TOOLS x10

A thin plastic rod 8.2 cm long carrying charge -0.022 µC is bent into a circular ring. What is the electric potential at the center of the ring, assuming V = 0 at infinity? Express your answer in kV, to at least one digit after the decimal point.

What is the magnitude of the electric field at the point (8.10i - 5.80j+9.40 k) m if the electric potential is given by V= 8.50xyz?, where Vis in volts and x, y, and z are in meters?

Consider a certain amount of a conducting liquid sprayed into 650 equal spherical drops. Each drop is charged to the same electric potential of 2.5 V (relative to the infinity where potential is zero). If all these 650 drops are combined into one large spherical drop, what is the electric potential of this large drop? The electric potential of the large drop, V = Units Select an answer ✓

There are three point charges in a system. The first is -9.34 micro coulombs and is located at (0,51.5)m. The second is -9.45 micro coulombs and is located at (-97.4,0) m.
