Options

Choose one · Correct answer highlighted

Explanation

Potential energy mgh=8×10×5=400J. As per NCERT, applying relevant law/formula with correct units and sign convention leads to 400 J. This satisfies dimensional consistency and physical conditions given, so option A is scientifically correct.
