Answer 1

Correct question :

Give examples of vector quantity .

Answer :

A vector quantity is any physical quantity that has both magnitude and direction and which obeys the vector law of addition .

Some examples of vector quantities are :

• Force
• Velocity
• Displacement
• Acceleration
• Torque
• Area

Vector law of addition is given by :

$\rm\vec{A } = \sqrt{ \vec{A \tiny1}^{2} + \vec{ {A \tiny2}}^{2} + 2 \vec{{A \tiny{1}}}{ \vec{A \tiny2}}cos \theta}$

Any physical quantity that may have both magnitude and direction but doesn't obeys Vector law of addition is not counted as a vector quantity . For example : Electric current .

The vector quantities are the cross product of any two vector quantities or a vector or scalar quantity while scalar quantity is a dot product of other two physical quantities .
