Question

Mass is a _____ quantity.

• A. scalar
• B. vector
• C. tensor
• D. none of these

Answer 1

The correct option is A

scalar

Explanation for Correct Option:

Option (A):

1. Mass is defined as the amount of matter present in a body.
2. Therefore, the mass of a body can be completely described using a magnitude.
3. We know that a scalar quantity is a quantity that contains only magnitude and no direction.
4. Hence, mass is a scalar quantity.

Explanation for Incorrect Option:

Option (B):

1. Vector quantity is a quantity that contains both magnitude and direction.
2. Hence, mass is not a vector quantity.

Option (C):

1. A tensor is a matrix that defines the relationship between an object and a vector space.
2. Hence, mass is not a tensor quantity.

Option (D):

1. Since one of the options is correct, “none of these” cannot be the correct answer.
