Magnetic scalar potential is defined as$\text{U}(\overrightarrow{\text{r}_2})-\text{U}(\overrightarrow{\text{r}_1})=-\int\limits^{\vec{\text{r}}_2}_{\vec{\text{r}_1}} \vec{\text{B}}.\text{d}\vec{\text{l}}.$
Apply this equation to a closed curve enclosing a long atraicht wire. The RHS of the above equation is then $-{\mu}_\text{o} \text{ i}$ by Ampere's law. We see that $\text{U}(\vec{\text{r}_2})\neq\text{U}(\vec{\text{r}_1})$ even when $\vec{\text{r}_2}=\vec{\text{r}_1}.$Can we have a magnetic acalar potential in this case?

Consider a small surface area of $1mm^2$ at the top of a mercury drop of radius 4.0mm. Find the force exerted on this area:
→- By the air above it.
- By the mercury below it and.
- By the mercury surface in contact with it. Atmospheric pressure $= 1.0 × 10^5$Pa and surface tension of mercury = 0.465N/m. Neglect the effect of gravity. Assume all numbers to be exact.
