positive charges and negative charges

When an electric field is applied in the path of cathode rays, they are deflected towards the positive plate of the electric field, which shows cathode rays are made up of negatively charged particle..

Charging by Friction - Keeping in mind the structure of the atom, we can easily explain charging by rubbing. When glass rod is rubbed with silk, some of the electrons from the atoms on glass are transferred to silk. Because there is a deficiency of electrons in the glass, it bec..

Keeping in mind the structure of the atom, we can easily explain charging by rubbing. When glass rod is rubbed with silk, some of the electrons from the atoms on glass are transferred to silk. Because there is a deficiency of electrons in the glass, it becomes positively h..

Similarly, if a positively charged rod is brought closer to a sphere ,the sphere acquires negative charge..

In order to identify the charge of a body we should use a charged electroscope. Let us say the electroscope is negatively charged. Now bring the unknown charged body 'X' near the cap of the electroscope. If the leaves diverge more the ..

We can charge bodies, i.e., make them positively charged or negatively charged by two different metho..

The e/m ratio of the anode rays obtained from hydrogen gas was found to be highest and equivalent to 9.58 x 10 4 C g - 1 . These particles carried a charge of 1.602 x 10 - 1 9 C. Thus, the mass of the positive particle from hydrogen gas is,..

Atomic Structure and Charges - The existence of negative and positive charges on these materials can be explained on the basis of the structure of the atom. Almost all the mass of an atom resides in a central nucleus which contains a number of tightly packed ..

The existence of negative and positive charges on these materials can be explained on the basis of the structure of the atom. Almost all the mass of an atom resides in a central nucleus which contains a number of tightly packed protons and neutrons. As the protons are ..

). When the charges are not similar they attract each other. (When the charged glass rod is brought near a charged ebonite rod, both the rods attract each other.) Thus like charges repel one another but unlike attract one another. This is known as law of elec..
