I 34. ou have a small glabe, which is mounted sa that is can spin on the polar axis and can be spun about a horizontal axis (so that the south pole can be on top). Give the globe a quick spin about horizontal axis also. Are there any points on the surface of the globe that are at rest? (choose the best alternative) 1) There are two points, fixed on the globe that are at rest 2There are two points that are instantaneously at rest, but these two points move around the globe in an apparently random fashion 3) At some times two points are instantaneously at rest but at other times there are no points at rest 4) There are no paints at rest until the globe stops spinning square plate of mass Mand edge L is shown in figure. Morment of inertial of the nate about the axis in the plane of plate and passing through one of its vertex making an angle 15 with its side as shown in figure is 35. 15 1) ML? 12 2) IML: 24 3) 7ML? 7ML 12 A disc of radius Ris rolling without slipping on a horizontal surface. Pis a point at 36 distance x above its centre O at a certain instant. The radius of curvature of the trajectory of Pat that instant is (R+x)' (R+x)* R 2)R +x 3) 4)- R-X R
