Question

A vector of magnitude $100$ units is inclined at ${30}^0$ to another vector of magnitude $80$ units. Then vector product is:

• A. $4000$
• B. $4000\sqrt{3}$
• C. $8000$
• D. $8000\sqrt{3}$

Answer 1

The correct option is A $4000$

$\overrightarrow{A}\times \overrightarrow{B}$ $=100\times 80\times sin{30}^0$ $=4000$
