A body of mass $10 kg$ is lifted to a height of $10 m$. The average value of gravity is $g = 10 m/s^2$. We need to calculate the work done.

1. Problem Description

A body of mass $10 kg$ is lifted to a height of $10 m$. The average value of gravity is $g = 10 m/s^2$. We need to calculate the work done.

2. Solution Steps

The work done $W$ in lifting an object is given by the formula:

$W = mgh$

where:

$m$ is the mass of the object,

$g$ is the acceleration due to gravity, and

$h$ is the height to which the object is lifted.

We are given:

$m = 10 kg$

$g = 10 m/s^2$

$h = 10 m$

Plugging in the given values, we get:

$W = (10 kg) * (10 m/s^2) * (10 m)$

$W = 1000 kg \cdot m^2/s^2$

$W = 1000 J$

3. Final Answer

The work done is $1000 J$.
