MCQ

A roller is mad e by joining together two cones at their vertices $O$. It is kept on two rails $AB$ and $CD$, which are placed asymmetrically (see figure) , with its axis perpendicular to $CD $ and its centre $O$ at the centre ofline joining $AB$ and $CD$ (see figure) . It is given a light push so that it $A$ starts rolling with its centre $O$ moving parallel to $CD$ in the direction shown. As it moves, the roller will tend to

A
go straight
B
tum left and right alternately
✓
turn left
D
turn right

✓

Answer

Correct option: C.

turn left

c
As shown in the diagram, the normal reaction of $AB$ on roller will shift towards $O$.

This will lead to tending of the system of cones to trun left.
