Practice question
Question
A 2.5kg mass falls from 8m onto a spring (k\=1000N/m). What is the maximum compression? (Take g\=10m/s2)
Explanation
Potential energy mgh=2.5×10×8=200J. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 200 J. This satisfies dimensional consistency and physical conditions given, so option A is scientifically correct.
