Answer 1

Assertion : Mass of an object is always zero

Reason : Mass of an object is the measure of its inertia and the substance contained by the body.

concept :

• Mass is the measure of substance contained by the body.
• It is also a measure of body's inertia, the resistance applied by the body when net force is applied on it.
• SI unit of mass is Kg.
• It is one of the seven fundamental quantities.
• Mass can't be zero because it is just quantity of matter in the body.

Therefore Assertion is false and Reason is true.
