A hemispherical bowl of uniform mass distribution of mass ‘M’ is at rest on frictionless horizontal ground sur- face. There is a small insect of mass 'm' on bowl at point ‘A’ of the bowl at rest. Now the insect moves with constant speed ‘v’ relative to bowl in vertical plane. Assume that insect does not slip on the bowl. When insect at point ‘P’ on the bowl the displacement of centre of mass of the system (bowl + insect) is :

A hemispherical bowl of uniform mass distribution of mass ‘M’ is at rest on frictionless horizontal ground sur- face. There is a small insect of mass 'm' on bowl at point ‘A’ of the bowl at rest. Now the insect moves with constant speed ‘v’ relative to bowl in vertical plane. Assume that insect does not slip on the bowl. When the insect is at point ‘P’ of the hemispherical bowl the acceleration of bowl is :

In a second ODI match between England and India Bhuwnesh kumar bowled his medium fast bowling. He starts his run up from the distance of 50m from the stumps (bowling end) and at the time of bowling a ball,his speed is 36(km)//(hr) and the speed of ball is 144(km)//(hr) . If his mass is 70 kg and mass of the ball is (1)/(4)kg and the heat produce in his body is one tenth of the total work done by him, then Select the incorrect statement :

A hemispherical bowl of uniform mass distribution of mass ‘M’ is at rest on frictionless horizontal ground sur- face. There is a small insect of mass 'm' on bowl at point ‘A’ of the bowl at rest. Now the insect moves with constant speed ‘v’ relative to bowl in vertical plane. Assume that insect does not slip on the bowl. When the insect reaches point ‘P’ of the hemisphere the displacement of hemisphere w.r.t. ground is :

A circular disc of radius 'R' is placed co-axially and horizontally inside and opaque hemispherical bowl of radius 'a', Fig. The far edge of the disc is just visible when viewed from the edge of the bowl. The bowl is filled with transparent liquid of refractive index mu and the near edge of the dise becomes just visible. How far below the top of the bowl is the disc placed ? .

A hemispherical bowl of radius R is set rotating about its axis of symmetry which is kept vertical. A small block kept in the bowl rotates with the bowl without slipping on its surface. If the surfaces of the bowl is smooth, and the angle made by the radius through the block with the vertical is theta , find the angular speed at which the bowl is rotating.
