#8 Storm clouds may build up large negative charges near their bottom edges. The earth is a good conductor, so the charge on the clouds attract an equal and oppositeLT charge on the earth under the cloud. The electric field strength near the earth depends on the shape of the earth's surface, as we can explain with a simple model. The top metal plate in the figure has a uniformly distributed negative charge. The bottom metal plate, which has a...

Storm clouds may build up large negative charges near their
bottom edges. The earth is a good conductor, so the charge on the
cloud attracts an equal and opposite charge on the earth under the
cloud. The electric field strength near the earth depends on the
shape of the earth's surface, as we can explain with a simple
model. The top metal plate in (Figure 1) has uniformly distributed
negative charge. The bottom metal plate, which has a high point,...

plates and the region between them, showing the distribution of
positive charge on the bottom plate and electric field lines
between the two plates with the correct direction of the field?
Part B. Where is the electric field
strongest?
A.At the border of the picture, farther from the high
point.

Discussion Question 1: Suppose that
you are hiding inside a large, hollow metal sphere that is resting
above the ground on an insulating layer. There is a large charge Q
placed on the sphere. (a) If your body is neutral, will you be
harmed if you touch the inside surface of the sphere? (b) Your
clothes produce a lot of static electricity and you have a small
charge –q. Will you be harmed if you touch the inside surface of
the...

Question 76)
Part 1)
A charged cloud system produces an electric field in the air
near Earth's surface. A particle of charge -2.1 × 10-9 C
is acted on by a downward electrostatic force of 4.0 ×
10-6 N when placed in this field. (a)
What is the magnitude of the electric field? (b)
What is the magnitude of the electrostatic force on a proton placed
in this field? (c) What is the gravitational force
on the proton? (d) What...

3.1 Pre-lab In the lab on electric potential and electric field lines, you noted that charged par- ticles produce electric fields and these electric fields, in turn, act on charged par- ticles. However, you then proceeded to produce an electric field geometry using conductors held at a particular electric potential. What happened to the electric charges? Electric charge and electric potential are closely related to each other. Putting charge on a conductor raises its electric potential. It is usually much...

Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...

1. Two identical metal balls are suspended by insulating threads. Both balls have the same net charge. In this problem, do not assume the balls are point charges Ball 2 a. Draw a separate free-body diagram for each ball. Label the forces to indicate: . the object exerting the force, the object on which the force is exerted, • the type of force (gravitational, normal etc.), and • whether the force is...
