Athin uniform rod, pivoted at O, is rotating in the horizontal plane with constant angular speed w,At time, t = 0, a small insect starts from O and moves with constant speed v with respect to the rod
towards the other end. It reaches the end of the rod at t = T and stops. The angular speed of the system remains
throughout. Themagnitude of the torque (| 
|) on the systemaboutO, as a function of time is best represented
by which plot ?

Three very large plates of same area are kept parallel and close to each other. They are considered as ideal
black surfaces and have very high thermal conductivity. The first and third plates aremaintained at temperatures
2T and 3T respectively. The temperature of the middle (i.e. second) plate under steady state condition is A bi-convex lens is formedwith two thin plano-convex lenses..Refractive index n of the first
lens is 1.5 and that of the second lens is 1.2. Both the curved surfaces are of the same radius of curvature R =
14 cm. For this bi-convex lens, for an object distance of 40 cm, the image distance will be
