What is the resultant of two displacement vectors having the same direction?

Question

a. The resultant is the sum of the two displacements having the same direction as the original vectors.

b. The resultant is the difference of the two displacements having the same direction as the original vectors

c. the resultant is the sum of the two displacements having the direction opposite to the direction of the original vectors.

d. the resultant is the sum of the two displacements having the direction perpendicular to the direction of the original vectors

Ya I totally do not understand any of this physics. I read the chapter on it that I was supposed to but none of it makes sense and I really don't know what it is. I think its a or b from reading but I just don't know.

Answer 1

A displacement vector has a magnitude (size) and a direction (like any other vector).
Now let's take one that is two meters in magnitude and East in direction.
Then we combine it with another that is six meters East.
Now if we move two meters East, then six meters East. I claim we would end up eight meters East. ---> a.

Answer 2

i think its B

Answer 3

I think b is answer
