Answer:
The Work Done is
Explanation:
Since , the equipment is pulled in horizontal horizontal plane.
Therefore, its normal reaction must be equal to its weight.
So, Normal reaction,
We know, frictional force ,
(Where N is Normal reaction and is coefficient of kinetic friction )
Therefore,
We know ,
( Here D is distance covered by the force)
Putting, D=1000 m.
We get , Work Done
Nothing will happen. The mercury and steel will not move. It’s just like filling a glass halfway with cement and then pouring water on top of it.
