A particle with charge q1 C is moving in the positive z-direction at 5 m/s. The magnetic field at its position is B-3 4j1T What is the magnetic force on the particle? A. (20i+15j) N B. (207-15j) N C. (-20i+15j) N D. (-20/-15) N E. none of these

D.

Explanation:

The statement is not correctly written, the correct form is now described:

A particle with charge is moving in the positive z-direction at 5 meters per second. The magnetic field at its position is . What is the magnetic force on the particle?

From classic theory on Magnetism, we remember that the magnetic force  exerted on a particle (), measured in newtons, is determined by the following vectorial formula:

(1)

Where:

- Electric charge, measured in coulombs.

- Velocity of the particle, measured in meters per second.

- Magnetic field, measured in teslas.

If we know that , and , then the magnetic force on the particle is:

Which corresponds to option D.

a) cold, dry

explanation:

continental polar masses are cold and dry air masses because the cold air cannot hold much moisture. as they move into warmer air, they can trigger precipitation.

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
