A vector has magnitude and directions.Does it have a location in space? Can it vary with time ? Will two equal vectors `veca` and `vecb` at different locations in space necessarily have identical physical effects? Give examples in supports for your answer.

A vector has both magnitude and direction. Does it mean that anything that has magnitude and direction is necessarily a vector ?The rotation of a body can be specified by the direction of the axis of rotation, and the angle of rotation about the axis. Does that make any rotation a vector ?

Find the angle between two vectors veca and vecb with magnitudes sqrt3 and 2 ,respectively having veca cdot vecb = sqrt6

Two vectors vecA and vecB have their resultant equal to either of them, the angle between them is

An object has moved through a distance. Can it have zero displacement ? If yes, support your answer with an example.

Find the magnitude of two vectors veca and vecb , having the same magnitude and such that the angle between them is 60^o and their scalar product is 1/2 .

Answer the following ad true or false : Two collinear vectors having the same magnitude are equal.
