Answer:
0
Explanation:
The displacement is zero since it goes in a full circle and ends up where it started.
Answer:
1. Direction of B is parallel to V
2. Magnetic field is most uniform between the flat, parallel magnetic poles of a c-shaped magnet
3. Doubling B would double the magnitude of the force on the proton
4. Magnetic field is strongest near the north and south poles
5. The initial direction of the proton is toward the right of the screen. The field deflects the proton toward the top of the screen
6. Assume that you are viewing the diagram on a flat computer screen. Perpendicular to the screen, pointing toward you.
7. A stationary point charge doesn’t generate a magnetic field in the space around it.
8. Proton enters magnetic field at a speed of 7.8 x 10^4, charge of proton equal to 1.6 x 10^-19 is 2.6 x 10^-14 N
9. A few times every million years
10. Magnitude |q|vB directed towards bottom of screen
Explanation:
The sum of angles in a regular pentagon is
180*(5 - 2) = 540°
Each internal angle is 540/5 = 108°.
Each vertex creates a line of symmetry to the midpoint of the opposite side,
as shown in the figure.
Answer: 5 lines of symmetry.
