B

Statement I is true, Statement II is true and Statement II is NOT the correct explanation for Statement I.

C

Statement I is true, Statement II is false.

D

Statement I is false, Statement II is true.

Text Solution

Verified by Experts

The correct Answer is:
A
The shape of the liquid is actually controlled by two forces viz. surface tension and gravitational force. When size of drop is small, surface tension and force gtgravitational force, which means net force is due to surface tension. is minimum when the surface area is minimum. So the drop `E` is spherical.
When the size of the drop is larger, gravitational forcegtsurface tension. It means net force is due to gravitational force. In this case, gravity of the drop at the minimum. So, the drop is no more spherical.
