Question Style in MHT CET Surface Tension PYQs

Every question in this PDF is a single-correct MCQ. Most are numerical and use the surface energy of a drop or the capillary rise formula.

Question Style	What it Tests
Splitting and joining drops	A mercury drop that splits into 1000 droplets, a spherical drop divided into 64 equal droplets, and three mercury drops joined into a big drop
Capillary rise	A liquid rising 2.4 cm in a capillary, a capillary of radius 0.35 mm inclined at 60° with the vertical, and a glass rod inserted into a capillary tube
Soap bubbles	Two soap bubbles of radii r₁ and r₂ with their inside pressures, a soap bubble surrounded by another bubble, and the work done in blowing a bubble
Floating bodies	A light metal disc of radius r floating on water, a steel coin of thickness t, a needle 7 cm long, and a wire that is not to sink
Water between plates	A water drop squeezed between two glass plates so that it spreads over a given area

How to Use the Surface Tension PYQ PDF for MHT CET

Start with the 2025 and 2026 papers first, because they hold 7 of the 28 questions.
Learn that splitting a drop into n drops needs work W = 4πR²T(n^(1/3) - 1) and changes the radius by n^(1/3).
For the floating questions, balance the weight against the vertical component of the surface tension force.
Solve year-wise PYQs by timing yourself, as time management is crucial.
Re-attempt only the questions you got wrong, and note which formula or step you missed.
