Answer: The work done to lift the 2 N rock was 6 Joules.

Step-by-step explanation:

Weight of the Rock = 2 Newtons

So, the force required to lift this rock will be equal to its weight or greater than its weight

Minimum force required to lift the Rock = 2 N

Displacement of the Rock when force was applied = 3 m,

Work Done: It is defined as product of force applied to the object into displacement of the object.

$\text{Work done}=Force* Displacement=2 N* 3 m=6 Nm=6 Joules$

The work done to lift the 2 N rock was 6 Joules.
