If A=(x1,y1,z1),B=~(x2,y2,z3),C=~(x3,y3,...

If `A=(x_1,y_1,z_1),B=~(x_2,y_2,z_3),C=~(x_3,y_3,z_3)` represent coordinates of the three vertices of a triangular lamina then find the centre of mass of the lamina.

Text Solution

Verified by Experts

The centre of mass lies on the centroid. Hence the coordinates of centre of mass `=(X,Y)((x_1+x_2+x_3)/3,(y_1+y_2+y_3)/(3))`
