In a certain region of space, the gravitational field is given by -k/r, where r=distance, k=const. if gravitational potential at r=r0 be v0,then what is the expression for the gravitational potential v? options
1)k log(r/ro)
2)k log(ro/r)
3)vo+k log(r/ro)
4)vo+k log(ro/r)
plz help me out
I will mark u as brainliest if u answer correct

The correct answer is option 3 .

Please check the answer once :)

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.
