A sperical ball of radius r and relative density 0.5 is floating in equilibrium in water with half of it immersed in water. The work done in pushing the ball down so that whole of it is just immersed in water is [ rho is the density of water]-

A cylinderical container of length L is full to the brim with a liquid which has mass density rho . It is placed on a weight scale, the scale reading is w. A light wall ball which would float on the liquid if allowed to do so, of volume V and mass m is pushed gently down and held beneath the surface of the liquid with a rigid rod of negligible volume as shown on the left Q. if instead of being pushed down by a rod, the ball is held in place by a thin string attached to the bottom of the container as shown on the right what is the tension T is the string?

A fixed thermally conducting cylinder has a radius R and height L_0 . The cylinder is open at its bottom and has a small hole at its top. A piston of mass M is held at a distance L from the top surface, as shown in the figure. The atmospheric pressure is P_0 . The piston is taken completely out of the cylinder. The hole at the top is sealed. A water tank is brought below the cylinder and put in a position so that the water surface in the tank is at the same level as the top of the cylinder as shown in the figure. The density of the water is rho . In equilibrium, the height H of the water coulmn in the cylinder satisfies

Water is filled in a container upto height H as shown in the figure . A small hole is board on the surface of a container at the depth h from the surface of water . What will be the distance of a point along the horizontal where the jet of the water strikes the ground ? For which value of h will this distance be maximum ? Also find this maximum distance.

Consider a water jar of radius R that has water filled up to height H and is kept on a stand of height h (see figure) through a hole of radius r(rltltR) at its bottom the water leaks out and the stream of water coming down towards the gound has a shape like a funnel as shown in the figure. it the radius of teh cross-section of water stream when it hits the ground is x. then.

A square box of water has a small hole located the bottom corners. When the box is full and sitting on a level surface, complete opening of the hole results in a flow of water with a speed v_(0) as shown in Fig. (a). when the box is still half empty, it is tilted by 45^@ so that hole is at the lowest point. Now the water will flow out with a speed of

In a thin spherical fish bowl of radius 10 cm filled with water of refractive index (4//3) , there is a small fish at a distance 4 cm from the centre C as shown in Figure. Where will the fish appear to be, if seen from (a) E and (b) F (neglect the thickness of glass)?

A mass of 2kg is put on a flat pan attached to a vertical spring fixed on the ground as shown in figure. The mass of the spring and the pan is negligible. When spring is pressed and released the mass executes a simple harmonic motion. The spring constant is 200 N"/"m . What should be the minimum amplitude of the motion so that the mass gets detached from the pan? (take g= 10 m"/"s^(2) )
