A uniform rod of length 200cm and mass 500g is balanced on a wedge placed at 40 cm mark. A mass of 2Kg is suspended from the rod at 20cm and another unknown mass m is suspended from the rod at 160cm mark as shown in figure. Find value of m such that the rod is in equilibrium.

[" 35.In the arrangement shown,a block of unknown mass "m_(3)" is connected to two blocks "],[" of known masses "m_(1)=8kg" and "m_(2)=4kg" by light inextensible strings.If the tension in "],[" the string joining block "2" and block "3" is "(m_(1)g)/(2)" ,find the mass of block "3" .Assume no "],[" friction."]

A bomb explodes into two pieccs of masses 4 kg and 8 kg. The velocity of 8 kg mass is 6 m/s. The KE of the other mass

A balance is made of a rigid rod free to rotate about a point not at the centre of the rod. When an unknown mass m is placed in the left pan, it is balanced by a mass m_(1) placed in the right pan and similarly when the mass m is placed in the right pan, it is balanced by a mass m_(2) in the left pan. Neglecting the masses of the pans, m is
