Explanation / Answer

Center of only table is (0, 0)

x1 = 0 and y1 = 0

and m1 = 14 kg

or pot,

x2 = L/2 and y = w/2 and m2 = 5 kg

(A) Xcm = (m1 x1 + m2 x2 ) / (m1 + m2)

= ( 0 + (5L/2))/(14 + 5)

= 5 L / 38 .......Ans

(B) Ycm = (m1 y1 + m2 y2 )/ (m1 + m2 )

= ( 0 + (5 w/2 )) / (5 + 14)

= 5 w / 38
