Question

From the circular disc of radius 4 R two small disc of radius R are cut off. The centre of mass of the new structure will be:

$\hat{i} \frac{R}{5} + \hat{j} \frac{R}{5}$
$- \hat{i} \frac{R}{5} + \hat{j} \frac{R}{5}$
$\frac{- 3 R}{14} (\hat{i} + \hat{ȷ})$
None

The correct answer is: $fraction numerator negative 3 R over denominator 14 end fraction left parenthesis i with hat on top plus ȷ with hat on top right parenthesis$
