A body of mass 10 kg is suspended by a string and is pulled a side with a horizontal force of 49 N. Find the tension in the string, if the body is in equilibrium under these forces.

Explanation

To solve the problem of finding the tension in the string when a body of mass 10 kg is suspended and pulled aside with a horizontal force of 49 N, we can follow these steps:

### Step 1: Calculate the weight of the body.
The weight (W) of the body can be calculated using the formula:
\[ W = m \cdot g \]
where:
- \( m = 10 \, \text{kg} \) (mass of the body)
- \( g = 9.8 \, \text{m/s}^2 \) (acceleration due to gravity)
