True or False there is force of repulsion between particles of matter

Forces of attraction between particles are strongest in

State three main characteristics of the particles of matter.

Consider a gold nucleus to be a sphere of redius 6.9 fermi in whichprotons and neutrons are distributed. Find the force of repulsion between two protons situated at largest separaton. Why do thes protons not fly apart under this repulsion

The force of repulsion between two point charges is F, when they are d distance apart. If the point charges are replaced by conducted sphereas each of radius r and the charges remain same. The separation between the centre of sphere isd, then force of repulsion between them is

An alpha - particle is the nucleus of a helium atom. It has a mas m=6.64xx10^-27 kg and as charge 1=+2e=3.2xx10^-19 c. compare the force of the electric repulsion between two alpha -particles with the force of gravitational attraction between them.

Assertion: Forces acting between proton-proton (f_(pp)) , proton -neutron (f_(pn)) and neutron -neutron (f_(n n)) are such that f_(pp) lt f_(pn)=f_(n n) . Reason: Electrostatic force of repulsion between two proton reduces net nuclear forces between them.

Cohesion is the force of attraction between particles of ....................(same/different) substances.
