## How do you find the x and y components of a vector sum?

The component method of addition can be summarized this way:

- Using trigonometry, find the x-component and the y-component for each vector.
- Add up both x-components, (one from each vector), to get the x-component of the total.
- Add up both y-components, (one from each vector), to get the y-component of the total.

## What are the x and y components of vector C⃗?

In physics, when you break a vector into its parts, those parts are called its components. For example, in the vector (4, 1), the x-axis (horizontal) component is 4, and the y-axis (vertical) component is 1.

**What are x and y components?**

These parts of the force are called the components of the force. The component that pushes right or left is called the x-component, and the part that pushes up or down is called the y-component. Mathematically, the components act like shadows of the force vector on the coordinate axes.

### What is the x-component of vector vector A?

The x-component of Vector A is opposite to the 15o angle. When finding components by drawing a right triangle around the given angle, you need to put in the signs explicitly. In this case, the x-component points to the left and so is negative. The y-component of Vector A is adjacent to the 15o angle.

### What is the y component of the electric field?

The y component of the electric field of an electromagnetic wave travelling in the +x direction through vacuum obeys the equation Ey = (375 N/C) cos [kx − (2.20 × 10 14 rad/s)t].

**What are the components of electric field?**

The E-field in Maxwell’s Equations is always a 3-dimension vector field. This means it has 3 components – an x-, y- and z-component that define the Electric Field in the x-, y- and z-directions.

## What is the resultant vector when three vectors are added together?

When these three vectors are added together in head-to-tail fashion, the resultant is a vector that extends from the tail of the first vector (6.0 km, North, shown in red) to the arrowhead of the third vector (2.0 km, North, shown in green). The head-to-tail vector addition diagram is shown below.

## How do you find the magnitude of the resultant vector (r)?

The 22.0 m, North side is the result of 2.0 m, South and 24.0 m, North added together. The 52.0 m, West side is the result of 16.0 m, West and 36.0 m, West added together. The magnitude of the resultant vector (R) can be determined using the Pythagorean theorem.

**How do you add two vectors with opposite directions?**

In actuality, it really is addition – the addition of vectors with opposite direction. Similarly, a northward and a southward component would also add together as a positive and a negative. Once the bottom row is accurately determined, the magnitude of the resultant can be determined using Pythagorean theorem.

### What is the degree of a vector in the second quadrant?

Noting that the vector is in the second quadrant (by the signs of its xand ycomponents) we see that 122° i s the correct answer. The results are depicted in the figure to the right. LEARNWe can check our answers by noting that the x- and the y- components of can be written as
