## Question

From the diagram above, a weight W = 60N is suspended horizontally by a string attached to a wall. Find the tension T on the string.

### Answer

**The answer to the above question for the tension of the string is 40√3**.

**Data**

Weight, W = 60N

Tension, T = ?

Angle, θ = 30^{0}

**Formula**

Since W = Tcosθ

We will apply the formula below to solve the problem

T = W / cosθ

### Solution

We will insert our data into the formula

Tension, T = W / cosθ = 60 / cos30^{0}

Since cos30^{0} = √3 / 2

Thus

T = 60 / ( √3 / 2 ) = 60 x (2 x √3) = 120√3

And 120√3 = 69.828 = 40√3

Therefore

T = 40√3

**Thus, the tension of the string is 40√3**.

**Hence, the solution to the question **“From the diagram above, a weight W = 60N is suspended horizontally by a string attached to a wall. Find the tension T on the string” **is 40√3**.
