Question

Vector quantities are expressed in

• A. magnitude only
• B. direction only
• C. magnitude and direction
• D. none of the above

Answer 1

The correct option is C

magnitude and direction

1. A physical quantity that can be completely expressed only, if its magnitude and direction are known is called a vector quantity
2. A car covers a distance of 45 km in an hour in exactly east direction. So, its velocity is 45 km/h-east. So velocity is a vector quantity.

Hence, (C) will be the correct answer.
