7000 Joules
We are given;
But, Force = mass × g (taking g as 10 N/kg)
Assuming we are given the distance moved by the object as 7 m
We can calculate the work done by the force
We need to know that;
Work done = Force × distance
Therefore;
Work done = 1000 N × 7 m
= 7000 Joules
Therefore, the work done by the force is 7000 Joules
