Assertion: Distance is a scalar quantity. Reason: Distance is the length of path traversed.

Assertion: Displacement of a body may be zero when distance travelled by it is not zero. Reason: The displacement is the longest distance between initial and final position.

Which of the following statements is incorrect? a) Path length is a scalar quantity whereas displacement is a vector quantity. b) The displacement depends only on the end points whereas path length depends on the actual path followed. c) The path length is always positive whereas displacement can be positive, negative and zero. d) The path length is always positive whereas displacement can be positive, negative and zero.

The shortest distance between the car and the motorcycle if their initial positions are as shown, will be :

Assertion - small displacement is a vector quantity. Reason Pressure and surface tension are also vector quanities.

These questions consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following five reponses (a) If both Assertion and Reason arecorrect and Reason is the correct explanation of Asserrtion. (b) If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion. (c ) If Assertion is true but Reason is false. (d) If Assertion is false but Reason is true. Assertion . Work done by constant force is equal to magnitude of force multiplied by displacement. Reason. Work done is scalar quantity. If may be positive, negative or zero.

Find the distance between the points A and B with position vectors hat i- hat j and 2 hat i+ hat j+2 hat kdot

A : for a moving particle distance can never be negative or zero. R : Distance is a scalar quantity and never decreases with time for moving object.

Statement-I : If the initial and final positions coincide, the displacement is a null vector. Statement-II : A physical quantity can not be called a vector, if its magnitude is zero.
