alleryFree liquid drops and bubbles are spherical if we neglect:
ADensity
BPressure
CMomentum
DGravity
Answer & Solution
Correct answer: D. Gravity
1. Surface energy alone would shape a free drop.
2. Gravity and air resistance pull it out of that shape.
3. With those neglected, the drop stays spherical.
