Question
A uniform thin rod of mass M and length L is standing vertically along the Y–axis on a smooth horizontal surface with its lower end at origin (0, 0). A slight disturbance at t = 0 causes the lower end to slip on smooth surface along the positive X–axis and the rod starts falling. The path followed by the centre of mass of the rod during its fall is a/an.
- Straight line
- Parabola
- Ellipse
- Circle
The correct answer is: Circle
x = 
cos 
; y = sin
= 1
x2 + y2 = 
= Circle
