Show that f= 2xy+z3+x2j+3xz2 is a conservative force field ,find potential energy, find work done in moving object from (1,_2,1) to ( 3,1,4)

since the work done in closed path for above function is independent of the path so this is a conservative field

Explanation:

As we know that

now from above 3 equations we have

since the work done in closed path for above function is independent of the path

so this is a conservative field

Now work done in moving the object is given as

this is a good question! i'll do some research and come back when i have the answer!

which piece of furniture will have the most inertia and give the furniture movers the most difficulty in moving?  

answer

a 75kg dining table
