Respuesta :
Your answer lies in between Diagram 3 and Diagram 4. You would add the sum of the two vectors to get your resultant, in which your answer comes out to be Diagram 3. ♥
Explanation :
Resultant of two vectors can be find out by adding two vectors together. We have two vectors [tex]\underset{a}{\rightarrow}[/tex] in up direction and[tex]\underset{b}{\rightarrow}[/tex] in right.
There resultant can be given by[tex]\underset{R}{\rightarrow}[/tex], which is the sum of two vectors.
So, diagram (3) shows correct answer.
