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,...

Written Question #1: Storm clouds may build up large negative charges near their bot- tom edges. The earth is a good conductor, so the charge on the clouds attract positive charges on the earth under the cloud. The electric field strength near the earth de- pends 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 plate is overall neutral...

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.

Suppose you place a charge q near a large metal plate. If q is attracted to the plate, is the plate necessarily charged? Yes, since only unlike charges can attract each other Yes, since only like charges can attract each other No, since a polarization charge could be induced in the plate No, since q can be attracted to an uncharged metal plate Question 8 (12.5 points) What would the electric field look like in a system with two parallel...

Question 5 (3 points) A horizontal dipole has the positive charge located at (+x, 0) and the negative charge located at (-x,0) where x is a very small distance. If we are looking at a point directly above the dipole (0, 5 m), and see an electric field of 9,141,100 N/C, determine the dipole moment of the dipole. Your Answer: Answer units Question 6 (3 points) A horizontal dipole has the positive charge located at (+x, 0) and the negative...

Two large parallel plates are separated by 20 cm. The top plate has a positive net charge, with charge density σ= 2 C/m^2, while the bottom plate has a negative charge density of equal magnitude. What is the magnitude of the electric field between the two plates? Remember that eO= 8.85x10^-12 F/m. a. 4.6x10A11 N/C 2.3x10411 N/C c. 1.7x10A11 N/C O b. d ON/C QUESTION 2 Two large parallel plates are separated by 20 cm. The top plate has a...

Two parallel, metal plates with separation distance d = 1.00 cm carry charges of equal magnitude but opposite sign. The plates are oriented horizontally. Assume the electric field between the plates is uniform, and it has a magnitude of 1,920 N/C. A charged particle with mass 2.00 ✕ 10−16 kg and charge 1.11 ✕ 10−6 C is projected from the center of the bottom negative plate with an initial speed of 1.11 ✕ 105 m/s at an angle of 37.0°...

2. Thave 2 equally strong positive charges that I've bolted to the ground. Where can I put a 3rd (mobile) test charge, such that it doesn't feel an overall force from them? What changes if one of those original charges is negative? 3. I have 2 conducting plates, both weighing mass M, with charges q1 and 92 (that I control) on each respectively. I bolt one plate to the ground so it can't move, and I want to levitate the...
