Short Answer

Which of the particles in Figure 22.47 has the greatest mass, assuming all have identical charges and velocities?

The particles ‘a’ in the figure has the greatest mass, assuming all have identical charges and velocities.

Step 1: Definition of Magnetic force

The magnetic force is always applicable on the moving charge and can be expressed as,

Where q and v are the charge and velocity of the charged particle and B is the applied magnetic field.

Step 2: Cause of Magnetic force

Charged particles move in a circular motion as a result of magnetic force, which is known as centripetal force, and the radius of the circular motion can be given as,

r mvqB

Where m is the mass of the charged particle.

If we keep the other parameters constant except mass, we can write that,

r ∞ m

Therefore, the particle with a higher radius will have the greatest mass, and we can see from the above figure that the particle with a higher radius is ‘a’.

Therefore, the particel with the greatest mass is a.

Is the Earth’s magnetic field parallel to the ground at all locations? If not, where is it parallel to the surface? Is its strength the same at all locations? If not, where is it greatest?

Consider a mass separator that applies a magnetic field perpendicular to the velocity of ions and separates the ions based on the radius of curvature of their paths in the field. Construct a problem in which you calculate the magnetic field strength needed to separate two ions that differ in mass, but not charge, and have the same initial velocity. Among the things to consider are the types of ions, the velocities they can be given before entering the magnetic field, and a reasonable value for the radius of curvature of the paths they follow. In addition, calculate the separation distance between the ions at the point where they are detected.

A wire carrying a 30.0‐A current passes between the poles of a strong magnet that is perpendicular to its field and experiences a 2.16‐N force on the 4.00 cm of wire in the field. What is the average field strength?

A cosmic ray electron moves at \({\rm{7}}{\rm{.50 \times 1}}{{\rm{0}}^{\rm{6}}}{\rm{ m/s}}\) perpendicular to the Earth’s magnetic field at an altitude where field strength is\({\rm{1}}{\rm{.00 \times 1}}{{\rm{0}}^{{\rm{ - 5}}}}{\rm{ T}}\). What is the radius of the circular path the electron follows?

(a) Aircraft sometimes acquire small static charges. Suppose a supersonic jet has a 0.500‐μC charge and flies due west at a speed of 660 m/s over the Earth’s south magnetic pole, where the 8.00×10‐5‐T magnetic field points straight up. What are the direction and the magnitude of the magnetic force on the plane? (b) Discuss whether the value obtained in part (a) implies this is a significant or negligible effect.
