If the field is in a vacuum, the magnetic field is the dominant factor determining the motion. Since the magnetic force is perpendicular to the direction of travel, a charged particle follows a curved path in a magnetic field. The particle continues to follow this curved path until it forms a complete circle. Another way to look at this is that the magnetic force is always perpendicular to velocity, so that it does no work on the charged particle. The particle’s kinetic energy and speed thus remain constant. The direction of motion is affected but not the speed.

A negatively charged particle moves in the plane of the paper in a region where the magnetic field is perpendicular to the paper (represented by the small × ’s—like the tails of arrows). The magnetic force is perpendicular to the velocity, so velocity changes in direction but not magnitude. The result is uniform circular motion.

The diameters of the main rotor and tail rotor of a single-engine helicopter are 7.56 m and 1.00 m, respectively. The respective

valentina_108 [34]

Answer:

Explanation:

Given

Diameter of main rotor $d_1=7.56 m$

Tail rotor $d_2=1 m$

$N_1=453 rev/min$

$N_2=4137 rev/min$

$\omega =\frac{2\pi N}{60}$

$\omega _1=\frac{2\pi 453}{60}=47.44 rad/s$

$\omega _2=\frac{2\pi 4137}{60}=433.28 rad/s$

Speed of the tip of main rotor $=\omega _1\times r_1=47.44\times \frac{7.56}{2}=179.32 m/s$

Speed of tail rotor $=\omega _2\times r_2=433.28\times \frac{1}{2}=216.64 m/s$

8) Now drop the magnetic ball of the same size down the section of copper tube. Currents are induced in the tube both above and

Kazeer [188]

Answer:

Explanation:

To have a deeper understanding of this. Let's begin with the acceleration due to gravity (g), with N pointing downward.

Since magnetic field lines originate in the north, field strength decreases for the upper disk and increases for the lower disk when the disk is in the center of two disks.

According to Lenz's theorem, current-induced would be so that the magnetic field due to this induced current opposes the magnetic field due to which there is an induced current, so induced current will be clockwise for the upper disk and anticlockwise for the lower disk.

If the south pole is pointing backward, the generated current will flow anticlockwise for the upper disk and clockwise for the lower disk.
