The radius of the ion's path in the magnetic field is determined by the ion's charge, speed, and the strength of the magnetic field.
The radius of the electron's spiral path is determined by its energy and the strength of the magnetic field it is moving through.
A charge moving perpendicular to a magnetic field experiences a force that is perpendicular to both the charge's velocity and the magnetic field direction. This force causes the charge to move in a circular path around the field lines, with the radius of the circle determined by the charge's speed and the strength of the magnetic field. This phenomenon is known as magnetic deflection.
An alpha particle is a positively charged particle, so it will experience a force perpendicular to both its velocity and the magnetic field direction. This force causes the alpha particle to move in a circular path due to the magnetic field's influence. The radius of the circle will depend on the velocity of the alpha particle and the strength of the magnetic field.
If the incident direction of an electron entering a magnetic field is not parallel to the field lines, the electron will experience a force due to the magnetic field. This force will cause the electron to move in a curved path known as a helix. The radius of this helical path depends on the velocity and charge of the electron, as well as the strength of the magnetic field.
according to the ampere's law . magnetic field is strongest in a loop or a plane. and about toroid the magnetic is strongest in the coil where the wire is rotated around it . Magnetic field is minimum inside and outside the toroid.
The amperage of a ring induced by a toroidal field in a magnetic particle test can be computed by using the formula: I = B * π * r, where I is the induced current, B is the magnetic field strength, and r is the radius of the ring. By calculating the product of the magnetic field strength, the radius of the ring, and π, you can determine the induced amperage in the ring.
raduis of amper loop is greater than than the radius of its own toriod..than this toriod is called ideal toriod
The radius of the ion's path in the magnetic field is determined by the ion's charge, speed, and the strength of the magnetic field.
volume of the cube - volume of the sphere = volume enclosed between the cube and sphere

The formula for the area of a circle is πr^2, where π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle. So, "pi r squared" refers to the area of a circle, calculated by multiplying π by the square of the radius. This formula is fundamental in geometry and mathematics for finding the area enclosed by a circle.
==================================Answer #2:I believe you want the volume of the shell ... the material between theinside and outside diameters ... whereas the first answer, above, gave youthe volume of the hole in the middle of everything. Here's my take on it:-- Volume of a sphere is 4/3 pi R3-- Volume enclosed by the outer radius is 4/3 pi (2)3-- Volume enclosed by the inner radius is 4/3 pi (1)3-- Volume of the material between them is4/3 pi (23 - 13) = 4/3 pi x 7 =28/3 pi = 29.32 m3. (rounded)The volume of a spherical shell is equal to the difference between the volume of a sphere with a radius of 2 m and a volume of a sphere with a radius of 1 meter:V= 29,321531433504736892318004910609 м3
because moon has small density and shorter radius than earth. specially density is more important for calculation of Gravity. there are some stars that have small radius but greater Gravity. why? because they have Larger density
Assuming equal velocity. The alpha particle has twice the charge but four times the mass so it would have the wider radius.
