Practice question
Question
A uniform square plate of side 6m and mass 9kg has one corner at (2,2) along the x- and y-axes. What is the position of its center of mass?
Explanation
For a uniform square, the center of mass is at the centroid. Vertices: (2,2),(8,2),(2,8),(8,8). CM: X = 2+62 = 5, Y = 2+62 = 5. Position: (5,5)m. As per NCERT, applying relevant law/formula with correct units and sign convention leads to (5,5). This satisfies dimensional consistency and physical conditions given, so option C is scientifically correct.
