BLOCK WITH A FORCE
THERE IS A BLOCK OF SIDE X METRES RESTING ON A FRICTIONLESS SURFACE
A FORCE F IS APPLIED AT THE LEFT TOP OF THE BOX(TAKE THE DIRECTION OF FORCE IS FROM LEFT TO RIGHT) HORIZONTALLY
NOTE: THE FORCE IS NOT AT THE CENTRE OF GRAVITY.
PROVE THAT THE BOX TENDS TO ROTATE ABOUT THE CENTRE OF GRAVITY ONLY.
ALSO PROVE THAT THE BOX WILL NOT TEND TO ROTATE ABOUT ANY OTHER POINT EXCEPT THE CENTRE OF GRAVITY.
The solution of the Posting is in the attached file.
