Practice question
Question
A 6kg block slides down a frictionless incline from 10m height. What is its speed at the bottom? (Take g\=10m/s2)
Explanation
Potential energy mgh=6×10×10=600J. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 600 J. This satisfies dimensional consistency and physical conditions given, so option A is scientifically correct.
