1.	If the resultant of any two vectors vec(A) and vec(B) is numerically equal to the either vector, the angle between the vectors can be:
Answer» `cos^(-1) (-(B)/(2A)) and cos^(-1) (-(A)/(2B))` `sin^(-1) ((A)/(B)) and cos^(-1) (-(B)/(2A))` `sin^(-1) (-(A)/(B)) and cos^(-1) (-(2A)/(B))` NONE of these Answer :A
