Question

Consider the following two statements

1.Linear momentum of a system of particles is zero

2.Kinetic energy of a system of particles is zero

Then

• A. implies 2 and 2 implies 1
• B. 1 does not imply 2 and 2 does not imply 1
• C. 1 implies 2 but 2 does not imply 1
• D. 1 does not imply 2 but 2 implies 1

Answer 1

The correct option is D

1 does not imply 2 but 2 implies 1

Because linear momentum is vector quantity where as kinetic energy is a scalar quantity.
