The centre of mass of a system of particles does not depend on
The center of mass of a system of particles is the average position of all the particles, weighted by their masses. It is an intrinsic property of the system and depends on the positions and masses of the individual particles. The position of the center of mass is calculated based on the distributioRead more
The center of mass of a system of particles is the average position of all the particles, weighted by their masses. It is an intrinsic property of the system and depends on the positions and masses of the individual particles. The position of the center of mass is calculated based on the distribution of mass within the system and the relative distances between the particles.
However, it must be stressed that these forces don’t cause an effect in determining the place of the center of mass at a given instant of time. As for a change in position with time for a given overall force acting upon the system, changing positions with external influences, its intrinsic position as for the configuration does not. For example, if a system of particles is exposed to gravity or an external push, then the center moves relative to the center of mass according to the net force. However, its position relative to the system remains unchanged.
The center of mass is determined purely by the spatial arrangement and masses of the particles, independent of any forces on the system, making it a very basic concept in explaining the motion and behavior of physical systems.

See lessState the condition under which a large magnification can be achieved in an astronomical telescope.
A large magnification in an astronomical telescope can be achieved when the objective lens has a long focal length, and the eyepiece has a short focal length. This increases the ratio of the objective's focal length to the eyepiece's focal length, enhancing magnification. For more visit here: https:Read more

Why is the value of angle of deviation for a ray of light undergoing refraction through a glass prism for different colours of light?
The angle of deviation differs for different colors of light because each color has a unique wavelength, leading to varying refractive indices in the glass prism. Shorter wavelengths, like violet, are refracted more, causing greater deviation, while longer wavelengths, like red, deviate less. For moRead more

How does the angle of minimum deviation of a glass prism vary, if the incident violet light is replaced by red light? Give reason.
The angle of minimum deviation decreases when violet light is replaced by red light. This is because red light has a longer wavelength, resulting in a lower refractive index for the glass prism. Consequently, red light undergoes less bending compared to violet light, reducing the angle of minimum deRead more

A disc is rolling on the inclined plane. What is the ratio of its rotation KE to the total KE?
When a disc rolls down an inclined plane, it has two types of kinetic energy: translational and rotational. The translational kinetic energy is due to the movement of the center of mass of the disc along the incline, while the rotational kinetic energy is due to the disc spinning around its axis asRead more
When a disc rolls down an inclined plane, it has two types of kinetic energy: translational and rotational. The translational kinetic energy is due to the movement of the center of mass of the disc along the incline, while the rotational kinetic energy is due to the disc spinning around its axis as it rolls.
For the solid disc, its moment of inertia plays an important role in determining how the energy is distributed between these two types of kinetic energy. For the disc that rolls without slipping, there exists a relationship between its linear velocity and its angular velocity, connecting the translational motion with the rotational motion.
When the total kinetic energy of the disc is analyzed, it is evident that the rotational kinetic energy is a part of the total energy. Once the contributions of both translational and rotational kinetic energy are evaluated, it is found that the ratio of the rotational kinetic energy to the total kinetic energy of a rolling disc is one to three. This means that for every part of kinetic energy contributed by rotation, three parts are from translation, thereby showing the balance between these two forms of energy in rolling motion.
