Statement I: The displacement of a body ...

Statement I: The displacement of a body may be zero, though its distance can be finite.
Statement II: If the bodt moves such that finally it arrives at the initial point, then displacement is zero while distance is finite.

A

Statement I is true, Statement II is true, Statement II is a correct explanation for Statement I.

B

Statemnt I is true, Statement II is true, Statement II is true, Statement II is false.

C

Statement I is true, Statement II is false.

D

Statement I is false, Statement II is true.

    An object has moved through some distance. Can its displacement be zero ?

    Displacement may be zero even when distance travelled is not zero ? Is not true ? Is the reverse also true ? Give examples.

    Statement I : The weight of a body at the centre of earth is zero Statement II : The mass of a body decreases with increase in depth below the surface of earth.

    Statement I: Distance and displacement are different physical quantities. Statement II : Distance and displacement have same dismension.

    Assertion : If the displacement of the body is zero, the distance covered by it may not be zero. Reason : Displacement is a vector quantity and distance is a scalar quantity.
