The force acting between two static electric charge is called electromagnetic force .Electromagnetic force is the firce due to interaction between two moving charges .This force is caused by the exchange of. proton between two charge particles . Gravitational force =In our universe due to its mass .Every body attracts each other .The force of attraction is called gravitational force . Strong nuclear force =The force that bind the electron or proton together in a nucleus ere called strong nuclear forces . Weak nuclear force=These are the forces appear only between alimantry particles of short life times ,involved in a nuclear process such as B- decay of a nucleus
