Kinematics Question 290

Question: The diagonals of a parallelogram are $2 \hat{i}$ and $2 \hat{j} .$ What is the area of the parallelogram

Options:

A) $\vec{b}$

B) $\vec{c}$

C) $\vec{b} . \vec{c}$

D) $\vec{b} \times \vec{c}$

Show Answer

Answer:

Correct Answer: D

Solution:

$\vec{a} . \vec{b} = 0$ i.e. $\vec{a}$ and $\vec{b}$ will be perpendicular to each other $\vec{a} . \vec{c} = 0$ i.e. $\vec{a}$ and $\vec{c}$ will be perpendicular to each other $\vec{b} \times \vec{c}$ will be a vector perpendicular to both $\vec{b}$ and $\vec{c}$ So $\vec{a}$ it’s parallel to $\vec{b} \times \vec{c}$
