A body can have zero average velocity but not zero average speed. Justify.

Option A

Option B

Option C

Option D

Solution

Average velocity is defined as the ratio of the total displacement to the total time taken, whereas average speed is defined as the ratio of total distance travelled to the time taken. Since displacement can be zero, therefore, we can have zero average velocity.
