Cho lực F ⃗=6x^3 i ⃗-4yj ⃗ tác dụng lên vật làm vật chuyển động từ A(-2,5) đến B(4,7). Vậy công của lực là:

The work done by along the given path C from A to B is given by the line integral,

I assume the path itself is a line segment, which can be parameterized by

with 0 ≤ t ≤ 1. Then the work performed by F along C is

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
