# Question #89967

##### 1 Answer

#### Answer:

Magnitude of resultant force

Angle

#### Explanation:

We need to use the **Law of parallelogram of vectors**.

The law states that when **two vectors (forces)** act on a particle at the same time **are represented** in magnitude and direction **by the two adjacent sides of a parallelogram** drawn from a point **their resultant vector is represented** by the **diagonal of the parallelogram** in magnitude and direction drawn from the same point.

As given in the above figure two forces

According to parallelogram law of vectors, Magnitude and Direction of Resultant

Let

Draw perpendicular

1. In right

2. In right

simplifying and taking square root of both sides we get

3.
