A scaled rod of length 1m is balanced at 40cm mark as shown in figure. A coin of mass 10gm is kept at 10cm mark in the balance situation. Find mass of rod.

A rod of length 2l is bent as shown in figure. Coordinates of centre of mass are

A metre scale is balanced on a knife edge at its centre. When a coin of mass 15 g is kept at the 12 cm mark, the scale is found to be balanced at 45 cm. What is the mass of the metre scale?

A metre scale is balanced on a knife edge at its centre. When a mass of 10 kg is kept at the 12 cm mark, the scale is balanced at 45 cm. What is the mass of the metre scale?

An uniform metre scale of weight 50 g is balanced at 60 cm mark, when a weight of 15 g is suspended at 10 cm mark. Where must a weight 100 g be suspended to balance metre scale.

A rod of mass 2kg and length 1m is pivoted at one end A and kept on a smooth surface. A particle of mass 500gm strikes the other end B of the rod and sticks to the rod. If particle was moving with the speed of 20m//s , what is the angular speed of the rod after collision ?

A uniform rod of length 50 cm is released in the vertical plane from the position shown in the figure. The rod is hinged smoothly at O. The angular speed of rod when it becomes horizontal is ( take g = 10m s^(-2) )

A composite rod comprising two rods of mass m and 2m and each of length l = 1 m as shown in the figure. Assume omega = 10 rad//s and m = 1 kg , the KE of the rotating composite rod is. .

A rod AB of mass M and length L is shown in figure. End A of rod is hinged and end B is lying on the ground. Find the Normal reaction by ground on the rod

A Iong slender rod of mass 2 kg and length m is placed on a smooth horizontal table. Two particles of masses 2 kg and 1kg strike the rod simultaneously and stick to the rod after collision as shown in fig. , If the two particles strike the rod in opposite direction, then after collision, as compared to the previous situation the rod will

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.
