As we discussed in concept

Potential Energy -

U_{f}-U_{i}= \int_{r_{i}}^{r_{f}}\vec{f}\cdot \vec{ds}

- wherein

U_{f}-final\: potential\: energy

U_{i}-initial \: potential\: energy

f-force

ds-small \: displacement

r_{i}-initial \: position

r_{f}-final\: position

 

 Remains Same (No Change) because potential energy is independent of velocity.


Option 1)

does not change

Option is correct

Option 2)

becomes twice to that of initial
 

Option is incorrect

Option 3)

becomes 4 times that of initial
 

Option is incorrect
