Question

Which vector has a y-component with a length of 1?

Answer 1

In this 2-dimensional graph, the x-component of each vector is the horizontal distance from the origin, while the y-component of each vector is the vertical distance from the origin. It can be seen that the c vector is 1 vertical unit away from the origin, which means that it has a y-component of 1.

Answer 2

Answer:

the length of the vector c is 1 along Y direction

Explanation:

As the graphical representation is given in this figure we can say the two components of the vectors are

height of the vector = Y components

horizontal distance = x component

so here we can say

$\vec a = 1\hat i + 3\hat j$

$\vec b = 3\hat i - 3\hat j$

$\vec c = -2\hat i + 1\hat j$

$\vec d = -3\hat i + 4\hat j$

So the length of the vector c is 1 along Y direction
