a rod of mass M and length L has moment of inertia,I=ML2/12
but it is only for a thin rod
here the rod is a line passing through centers of disks,it's M.I constitute only small part of total M.I of the arrangement
here,the moment of inertia the arrangement is comparable to the M.I of a rod of...
i think charges will go to the surfaces
if there is excess charge(suppose +ve) inside the metallic sphere in static situation it will produce electric field.then free electrones move to the +ve charge to neutralize it.movement of free electrones cause +ve charge somewhere else.ie,the metallic...
sir I have a doubt why component of gravitational force doesn't matter here when tap is at an angle
considering a fluid part it has 2 forces on it 1 by the pressure or weight created by fluid part above it and gravitational force on it.
please coeerct me if I am wrong
the rotation of body3 also influence the centrifugal force on the cursor and distance it moved against spring force
when body3' z3 axis become parallel to z2 axis total mass=m2+m3 cursor moves x distance from equilibrium position where kx=(m2+m3)(a+x)(theeta point)^2
when body3 moves 90degrree...
