Practice question
Question
A soap film supports 3.0 × 10⁻²N over a 50 cm slider. What is the surface tension?
Explanation
Given:
A soap film supports 3.0 × 10⁻²N over a 50 cm slider. What is the surface tension?
Formula:
S = F/2 l.
Substitution & Calculation:
F = 3.0 × 10⁻²N, l = 0.5 m . S = frac3.0 × 10⁻²² × 0.5 = 0.03 N/m .
Final Result:
The computed value matches expected outcome and confirms correct choice as per latest NCERT 2026-27.
