A solid sphere of density `eta (gt 1)` times lighter than water is suspended in a water tank by a string tied to its base as shown in fig. if the mass of the sphere is `m` then the tension in the string is given by

A sphere of radius 25 cm and mass 1 kg is hung by a string of negligible mass and length 40 cm, then tension in the string is -

A uniform rod of length 1 and mass m is suspended by two vertical inextensible string as shown in the fig. The tension in the left string when right string snaps, is

A uniform sphere of weight W and radius 3 m is being held by a frictionless wall as shown in the figure. The tension in the string will be (length of the string is 2m):

In the arrangement shown in the figure the mass M is very heavy compared to m (M gt gt m) . The tension T in the string suspende from the ceiling is

In the arrangement shown in the figure the mass M is very heavy compared to m (M gt gt m) . The tension T in the string suspende from the ceiling is

A metallic sphere of mass 3 kg in air is held by a string so as to be completely immersed in a liquid of relative density 0.8. The relative density of metallic sphere is 10. The tension in the string is :-

A metallic sphere of mass 3 kg in air is held by a string so as to be completely immersed in a liquid of relative density 0.8. The relative density of metallic sphere is 10. The tension in the string is :-

Two solid uniform spheres each of radius 5 cm are connected by a light and totally immersed in a tank of water. If the specific gravities of the pressure are 0.5 and 2, find the tension in the string and the contact force between the bottom of the tank and the heavier sphere.
