Where does the centre of maIf $\hat{i}$, $\hat{j}$, $\hat{k}$ are right-handed orthogonal unit vectors, then $\hat{i} \times \hat{j}$ equA uniform L-shaped thin lamina of total mass 3 kg is made of three identical 1 m × 1 m squares as shown in theFor a homogeneous (uniformly dense) thin circular disc, the centre of mass lies at:A projectile is launched and follows the parabolic trajectory shown in the figure. Midway through its flight iThree particles of masses 100 g, 150 g and 200 g are placed at the vertices O(0, 0), A(0.5, 0) and B(0.25, 0.2
