Question

A laminar rigid body is pressed between two parallel guides moving in horizontal directions with opposite velocities $v_{1}$ and $v_{2}$ . At a certain instant of time, the points of contact between the ingot and the guides lie on a straight line perpendicular to the directions of velocities $v_{1}$ and $v_{2}$ . Choose the correct statement(s) :-

Assume the body rolls without slipping at both guides.

Instantaneous axis lies on the line joining the contacts, at distance x from the upper guide

$\frac{v _{1}}{x} = \frac{v _{2}}{ℓ - x} \Rightarrow x = \frac{v _{1} ℓ}{v _{1} + v _{2}}$

Speed = ω × distance from this axis, so equal speeds lie on circles centred at it

The axis point is the only point at rest
