The interaction energy of London forces between two particles is proportional to $r^x$, where $r$ is the distance between the particles. The value of $x$ is
1 3
2 -3
3 -6
4 6
Explanation:
According to London forces, "Greater than Polorisability of the interacting particles greater is the magnitude of interaction energy." The energy of interaction force $\propto \frac{1}{r^6}$ where, $r=$ distance between particles. The interaction energy of London forces is inversely proportional to sixth power of the distance between two interacting particles.

In the modern periodic table the acidic nature of oxides
1 Increases from left to right and decreases from top to bottom
2 Decreases from right to left and increases from top to bottom
3 Remains same across a period and increases from top to bottom
4 Decreases from left to right and remains the same down the group
Explanation:
Acidic nature increases from left to right and decreases top to bottom in modern periodic table because the electronegativity decreases down the group. Electronegativity is the property of the element to attract electron pairs. When the metal is more electropositive, it has more basic oxide in nature and less in acidic character.
