1. A vector is not changed if

(a) it is rotated through an arbitrary angle

(b) it is multiplied by an arbitrary scalar

(c) it is cross multiplied by a unit vector

(d) it is slid parallel to itself.

Explain what does (d) mean

ANSWER→

A vector is changed whenever the direction or the magnitude of the drawn line is altered to any extent. Hence, a vector definitely changes if it is rotated through an arbitrary angle or cross multiplied by a unit vector, as the direction of the vectors changes in both cases.
