Question

The displacement of an object if it returns to its initial position after covering 50 kms is:

a. 0 km

b. 50 km

c. 100 km

d. None of these

​

Answer 1

Answer

a . 0 km

Explanation

Displacement is defined as the shortest distance between two points i.e., final and initial points .

A ------<------------->------- B ( 50 km )

Here in this case , Object returns to it's initial position i.e., A after covering 50 km .

So the initial and final positions are same .

⇒ Displacement = 0 - 0 km

⇒ Displacement = 0 km

So , displacement is 0 km

Hence , Option a is correct
