If cathode ray is attracted towards north pole of magnet, then do negatively charged ebonite rod get attracted towards north pole?
rays get easly attracted than solids
yes it will be attracted by north pole
To determine whether a negatively charged ebonite rod would be attracted to the north pole of a magnet, we need to consider the behavior of charged particles and the interaction between charges and magnetic fields.
First, let's understand the behavior of a cathode ray in a magnetic field. A cathode ray is a beam of electrons traveling in a vacuum tube. Electrons are negatively charged particles, and when a magnetic field is applied perpendicular to their motion, they experience a force. This force acts as a result of the interaction between the moving charge (the electrons) and the magnetic field. According to the right-hand rule, the force on moving negatively charged particles is perpendicular to both the direction of the magnetic field and the direction of the particle's velocity.
In this case, if the cathode ray is attracted towards the north pole of the magnet, this means that the force experienced by the electrons is directed towards the north. So, the electrons are deflected in such a way that they are drawn towards the north pole of the magnet.
Now, let's consider the negatively charged ebonite rod. Ebonite, or hard rubber, can be negatively charged through a process called rubbing. When an ebonite rod is charged negatively, it gains an excess of electrons and thus becomes negatively charged.
When a negatively charged ebonite rod is placed near a magnet, it will also experience the force resulting from the interaction between its negative charge and the magnetic field. Since the rod carries negative charge, which is the same charge as the electrons, it will experience a force similar to the electrons in the cathode ray. Therefore, a negatively charged ebonite rod would also be attracted towards the north pole of the magnet.
To summarize, based on the behavior of charged particles in a magnetic field, we can conclude that a negatively charged ebonite rod would be attracted towards the north pole of a magnet.
