Two persons of equal heights are carrying a long uniform wooden plank of length `l` . They are at distance `(l)/(4)` and `(l)/(6)` from nearest end of the rod. The ratio of normal reation at their heads is

The mass per unit length of a non-uniform rod of length L is given by mu= lamdaxx2 ​, where lamda is a constant and x is distance from one end of the rod. The distance of the center of mass of rod from this end is :-

The mass per unit length of a non-uniform rod of length L is given by mu = lambdax^2 , where lambda is constant and x is distance from one end of the rod. The distance of the center of mass of rod from this end is

A boy and a man carry a uniform rod of length L,horizontally in such a way that the boy gets (1)/(4) th of the load. If the boy is at one end, the distance of the man from the other end is :

A mass m is at a distance a from one end of a uniform rod of length l and mass M. Find the gravitational force on the mass due to tke rod.

A mass m is at a distance a from one end of a uniform rod of length l and mass M. Find the gravitational force on the mass due to the rod.
