Approved Tutor Answer15 Years agodistance of any corner from center is d =a/sqrt3... (a is side of triangle)
moment of inertia of system is I=(I1+I2+I3)
mass and distance from axis of rotation is same for all hree particles so I1=I2=I3
total moment of inertia I = 3I1 = md2 =3(0.1. a2 /3)=0.4kg-m2
hence option A is correct
Approved Tutor Answer15 Years agoall the masses are kept at a distance of 2/31/2 m from the axis at the centroid.
there fore m.i. of each mass at the axis willl be same i.e.=0.4/3kgm2 on adding all the three moments of inertia it =0.4kgm2
thus according to me the answer is <a> if its incorrect please send me the correct explanation if possible
plz solve my problem &give me list of reagents in org chem with there spatial feachers. !!!!!!!!!!!!!!!!!!!
plz help me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
