Which of the following statements describes a relationship between the forces
described by Coulomb's Law and the forces described by Newton's Law of
Universal Gravitation?
In atoms, gravitational forces are weaker than electrical forces.
Gravitational forces and electrical forces are attractive forces only.
A.
В.
С.
Gravitational forces act at any distance: whereas, electrical forces act at very
short distances only.
D.
As the distance between objects increases, electrical forces increase, whereas
gravitational forces decrease.
If you have three parallel wires in the same plane, with currents in the outer two running in opposite directions, is it possible for the middle wire to be repelled by both? Attracted by both? Explain.
Current flows along a thin, infinite sheet as shown in the accompanying figure. The current per unit length along the sheet is J in amperes per meter. (a) Use the Biot-Savart law to show that B = μ0 J / 2 on either side of the sheet. What is the direction of B → on each side? (b) Now use Ampère’s law to calculate the field.
