Find the work W done by the 30-newton force

## Answer

## General guidance

Initially, find the component of the applied force on the object.

Finally, use the expression for work done and then substitute the values of force and distance given in the question to calculate the work done by the given applied force.

Work done is defined as the product of the force and the distance over which the force is applied.

The work done can be expressed as,

Here, is the work done, is the applied force, is the displacement and is the angle between the applied force and the displacement.

The expression for the component of the applied force is,

Here, is the *x* component of the force.

## Step-by-step

### Step 1 of 2

The free body diagram shows the force acts on the block in all the sides and calculate component of the applied force alone from the figure 1.

Here, the applied force is resolved into two components.

The component of the applied force is,

Substitute for and for .

The free body diagram is drawn to show the applied force is divided into the two component in the figure 1 they are horizontal component of force is mentioned as and the vertical component of the applied force is mentioned as .

### Step 2 of 2

The work done by the applied force is given by,

Substitute for and for .

**The work done by the **** force is ****.**

The work done by the applied force depends upon the displacement, force and the angle between the force and displacement.

### Answer

**The work done by the **** force is ****.**

### Answer only

**The work done by the **** force is ****.**
