A uniform square lamina of side 4m and mass 8kg has one corner at the origin and lies along the x- and y-axes. What is t
For a uniform square, the center of mass is at the centroid. Vertices: (0,0),(4,0),(0,4),(4,4). CM: X = 0+42 = 2, Y = 0+42 = 2. Position: (2,2)m. As per NCERT, applying relevant law/formula with correct units and sign convention leads to (2,2). This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
