Charge on alpha- particle is

Find the charges on different particles.

What is the origin of charge on colloidal particles?

Name the three constituents of an atom and state mass and charge of each. How are they distributed in an atom ?

Two particles having charge Q_(1) and Q_(2) , when kept at a certain distance exert a force F on each other . If the distance between the two particles is reduced to half and the charge on each particle is doubled , the force between the particles would be

Draw a neat labeled diagram representing an atom. Name the three sub-atomic particles in the atom & represent them symbolically showing the mass & charge of each. State where the sub-atomic particles are present in the atom.

Three paricles, each of mass m and carrying a charge q each, are suspended from a common pointby insulating massless strings each of length L. If the particles are in equilibrium and are located at the corners of an equilateral triangle of side a, calculate the charge q on each particle. Assume Lgtgta .
