( overset arrow r)c m=(2 × (( hati/2) + hatj) + 2 × ( hati + (5 hatj/2))/4) overset arrow rc m=(3/4) hati+(7/4) hatj

Q. The coordinates of the centre of mass of a uniform flag-shaped lamina (thin flat plate) of mass $4 k g$ . (The coordinates of the same are shown in the figure) are:

$(1.25 m, 1.50 m)$

$(0.75 m, 1.75 m)$

$(0.75 m, 0.75 m)$

$(1 m, 1.75 m)$

$(r \to)_{c m} = \frac{2 \times ( \frac{i ^}{2} + j ^ ) + 2 \times ( i ^ + \frac{5 j ^}{2} )}{4}$
$r \to_{c m} = \frac{3}{4} \hat{i} + \frac{7}{4} \hat{j}$

Q. The coordinates of the centre of mass of a uniform flag-shaped lamina (thin flat plate) of mass 4kg . (The coordinates of the same are shown in the figure) are:

(1.25m,1.50m)

(0.75m,1.75m)

(0.75m,0.75m)

(1m,1.75m)
