Chapter 17: Problem 34

Draw some electric field lines and a few equipotential surfaces outside a negatively charged hollow conducting sphere. What shape are the equipotential surfaces?

Short Answer

Expert verified
Answer: The equipotential surfaces outside a negatively charged hollow conducting sphere are spherical in shape and centered on the sphere itself.

Step by step solution

01

Draw the sphere and its electric field lines

Begin by drawing a negatively charged hollow conducting sphere. Electric field lines around the sphere should point inward, towards the negatively charged surface of the sphere. The lines should be evenly spaced around the sphere.
02

Determine the direction of equipotential surfaces

Recall that equipotential surfaces are always perpendicular to the electric field lines. Therefore, equipotential surfaces around the negatively charged sphere will be centered on the sphere and have a spherical shape.
03

Draw equipotential surfaces

Start with one equipotential surface close to the sphere, with a spherical shape centered on the sphere. As you move further away from the sphere, draw additional equipotential surfaces with a larger radius than the previous surface. These surfaces should also maintain a spherical shape and be centered on the sphere.
04

Analyze the shape of the equipotential surfaces

As we can see from steps 2 and 3, the equipotential surfaces around the negatively charged hollow conducting sphere have a spherical shape, centered on the negatively charged sphere. In conclusion, the equipotential surfaces outside a negatively charged hollow conducting sphere are spherical in shape and centered on the sphere itself.

Assume a dielectric strength of \(3.0 \mathrm{kV} / \mathrm{mm}\) for air.
Find the electric potential energy for the following array of charges: charge \(q_{1}=+4.0 \mu \mathrm{C}\) is located at \((x, y)=(0.0,0.0) \mathrm{m} ;\) charge \(q_{2}=+3.0 \mu \mathrm{C}\) is located at \((4.0,3.0) \mathrm{m} ;\) and charge \(q_{3}=-1.0 \mu \mathrm{C}\) is located at (0.0,3.0) \(\mathrm{m}\)
A parallel plate capacitor has a charge of \(5.5 \times 10^{-7} \mathrm{C}\) on one plate and \(-5.5 \times 10^{-7} \mathrm{C}\) on the other. The distance between the plates is increased by \(50 \%\) while the charge on each plate stays the same. What happens to the energy stored in the capacitor?

(Assume the gold nucleus is held in place by other gold atoms and does not move.)
