Question

if the displacement of a particals is equal to zero, then its distance is. Options are 1 must be equal to zero. 2 can't be equal to zero. 3 can be negative. 4 may or may not be equal to zero.

Answer 1

4) may or may not be equal to the zero

Answer 2

hey mate
4) may or may not be equal to zero is the right answer .
here is your explanation
suppose a car make a round trip of a circular field and reached the same point from where it starts the motion then, the distance covered by the car is equal to circumference of the circle and it's depend on radius of circle of which may be or may not be equal to zero.but the displacement by the car is equal to zero because the initial and final position are same.
hope it helps you.
