Question

Consider the following two statement:
I. Linear momentum of a system of particles is zero.
II. Kinetic energy of a system of particles is zero.
Then
(a) I implies II but II does not imply I.
(b) I does not imply II but II implies I.
(c) I implies II and II implies I.
(d) I does not imply II and II does not imply I.

Answer 1

option b is the correct.

kinetic energy is a scalar quantity and a Momentum is a vector quantity.

kinetic energy can only be zero when all the velocity is zero and if all the velocity is zero then linear momentum is also zero.

But if linear momentum is zero.it can be possible in two ways:-
(i) when all the velocity is zero
(ii) when the velocities are in opposite direction.

for (ii) kinetic energy cannot be zero.

PLEASE MARK BRAINLIST.
