and in that order, are the vertices of a regular hexagon with centre origin. If the position vectors of the vertices and are respectively, and , then is equal to?
Explanation for the correct option:
Find the value of :
Let is the center origin of the regular hexagon
are the vertices of given regular hexagon in that order
and will be with equal magnitude but in opposite direction.
Now,
Put the value and in ,
Hence, option ‘A’ is correct.
