The angle between the two force of magnitude 20n and 15n is 60 degrees (20n force being horizontal) determine the resultant in magnitude and direction

The magnitude of the resultant is 30.4 N.

The resultant angle direction is 25.3°.

Explanation:

To find the resultant of the magnitude and direction for given forces “P” and “Q” are 20 N and 15 N respectively, the angle (θ) between them is 60°.

We know that from triangle law of forces,  

Substitute the given values in the above formula,

R = 30.4 N

The magnitude of the resultant is 30.4 N.

To find the direction of the resultant we know that

Substitute the given values in the above formula,

Resultant angle=25.3°

The resultant angle direction is 25.3°.
