Test: Scalars and Vectors (May 12) - Question 1

Which of the following is not a scalar quantity?

Detailed Solution for Test: Scalars and Vectors (May 12) - Question 1

Impulse (I)

Since force is a vector quantity and impulse is the product of the sudden force applied and the time interval to bring equivalent the system. So Impulse also a vector quantity which have same direction to the force applied.

Test: Scalars and Vectors (May 12) - Question 3

A vector is not changed if

Detailed Solution for Test: Scalars and Vectors (May 12) - Question 3

When a vector is displaced parallel to itself, neither its magnitude nor its direction changes.

Test: Scalars and Vectors (May 12) - Question 4

Which of the following statements.is false regarding the vectors?

Detailed Solution for Test: Scalars and Vectors (May 12) - Question 4

The magnitude of a vector is a pure number. Each component of a vector is also a vector. The resultant of two vectors can be zero only if they have the same magnitude and opposite directions.

Test: Scalars and Vectors (May 12) - Question 5

Which of the following pairs of vectors are parallel?

Detailed Solution for Test: Scalars and Vectors (May 12) - Question 5

Test: Scalars and Vectors (May 12) - Question 6

The position of a particle in a rectangular co-ordinate system is (3, 2, 5). Then its position vector will be:

Detailed Solution for Test: Scalars and Vectors (May 12) - Question 6

The position vector of a particle in a rectangular coordinate system is given by the coordinates (x, y, z) as:
Position vector = 
In this case, x = 3, y = 2, and z = 5, so the position vector is:
Position vector = 
So, the correct answer is Option B.

Test: Scalars and Vectors (May 12) - Question 7

A scalar quantity is one that:

Detailed Solution for Test: Scalars and Vectors (May 12) - Question 7

A scalar quantity is a physical quantity that has magnitude but no direction. This means that it is independent of the coordinate system or the orientation of axes used to describe it. Regardless of how you choose to set up your coordinate system or the direction in which you measure the scalar quantity, its value remains the same.

Test: Scalars and Vectors (May 12) - Question 8

The operation used to obtain a scalar from two vectors is ______

Detailed Solution for Test: Scalars and Vectors (May 12) - Question 8

Dot product of two vectors gives a scalar quantity as the output. Cross product gives a vector as the output. It is also known as scalar product.

Test: Scalars and Vectors (May 12) - Question 9

The operation which does not give you a vector as an output from two vector inputs is ______

Detailed Solution for Test: Scalars and Vectors (May 12) - Question 9

Vector addition and subtraction give a vector as the output. Cross product also gives a vector as the output. Only Dot product gives a scalar after acting on two vectors.

Test: Scalars and Vectors (May 12) - Question 10

Which one of the following operations is valid?

Detailed Solution for Test: Scalars and Vectors (May 12) - Question 10

Only operations valid for vector with scalars are multiplication and division. A vector can be multiplied or divided by a scalar. Other operations like addition and subtraction are not valid for vectors with scalars.
