A uniform rod of mass `M` and length `L` rests on two supports. A ball of mass `m=M//3` is placed at distance `L//8` from the center as shown. Find reactions at supports.

A uniform board of mass M and length L rests on two spring scales. A person of mass m stands at a distance l from one end as shown in Fig. (a) The board and person are at rest. What is the reading of the two scales?

Figure shows two uniform rods of mass M and length l placed on two perpendicular lines. A small point mass m is placed on the point of intersection of the two lines. Find the net gravitational force experienced by m.

A uniform rod of mass m and length L is suspended through two vertical strings of equal lengths fixed at ends. A small object of mass 2m is placed at distance L//4 from the left end. Find the tensions in the two strings.

(a) A uniform rod of mass M and length L is placed at distance L from a point mass m as shown. Find force on m (b) A semiconductor wire has a length L and mass M . A particle of mass m is placed at the centre of the circle. find the gravitational attraction on the particle due to the wire.

A uniform rod of length L (in between the supports) and mass m is placed on two support A and B . The rod breaks suddenly at length L//10 from the support B . Find the reaction at support A immediately after the rod breaks

A thin uniform rod of mass m and length l is kept on a smooth horizontal surface such that it can move freely. At what distance from centre of rod should a particle of mass m strike on the rod such that the point P at a distance l/3 from the end of the rod is instantaneously at rest just after the elastic collision?
