Question

Three pieces of iron uniform thickness n mass m,m,2m respectively placed at corners of triangle having coordinates (2.5,1.5) (3.5,1.5) & (3,3) find the centre of mass of system​

Answer 1

Answer:

Explanation:

:

Here, m1=m,m2=m,m3=2m

x1=2.5,x2=3.5,x3=3,

y1=1.5,y2=3.5,y3=3.

∴xcm=m1x1+m2x2+m3x3m1+m2+m3

=m×2.5+m×3.5+2m×3m+m+2m=3

ycm=m1y1+m2y2+m3y3m1+m2+m3  

=m×1.5+m×1.5+2m×3m+m+2m=2.25
