Question

What are the first two steps for finding the magnitude of the resultant vector?

A.find the square of the first horizontal vector and the square root of the first vertical vector
B.find the square root of the first horizontal vector and the square root of the second horizontal vector
C.find the sum of the two horizontal vectors and the sum of the two vertical vectors D.find the difference between the two horizontal vectors and the difference between the two vertical vectors

Answer 1

C is gonna be your answer

Answer 2

Option C is right.

Explanation:

Resultant vector is the sum of two vectors.

i.e. addition of horizontal component and addition of vertical components.

For example, if ai+bj is one vector and ci+dj be another vector,

resultant vector = a+ib+c+id

= (a+c)+i(b+d)

i.e. option c is right
