Which particle revolves around the centre of atom___

The classical concept of atomic structure is that negative charges are uniformly distributed inside a sphere of radius R keeping the nucleus of positive charge Ze at the centre of that sphere. An atom as a whole is electrically neutral. find out the electric field at a distance r from the nucleus, according do this atomic model.

A non-conducting disc of radius a with uniform positive surface charge density sigma is placed on the ground with its axis vertical. A particle of mass m and positive charge q is dropped along the axis of the disc from a height H with zero initial velocity. Charge per unit mass of the particle is q/m = (4 epsilon_0 g)/(sigma) . (ii) Find the height for its equilibrium position.

State whether True or False : The positive charged particle of atom is proton.
