1We know the relation K.E=p2/2m where p is momentum and m is mass.If energy is 0 then according to me its momentum must be 0.
if total energy of a particle is zero,is its linear momentum neccesarily zero????xplain ur answer too!

1the total energy is PE+KE. here the total energy is zero implies that K. E is zero as Ankit says, because PE can be assigned to a system and not a particle (eg. gravitational PE exists if there is a gravitational field which is caused by the presence of mass somewhere else and potential energy is given the to the system- particle+mass...... same with electric)
so, i think linear momentum is zero as its velocity is zero
