Vectors X and Y are in the shown directions.


Which of the following shows the sum of the two vectors?

A.
B.
C.
D.


参考答案:  A


本题详细解析:

To get the direction of the sum, we have to rearrange these vectors.

We can arrange them to start from the same point and complete the parallelogram, and then the diagonal from the starting point will be the sum vector.

Using any method will give the same direction of the vector, which is in the same direction as choice A.
