Question

For the adjoining diagram, a triangular lamina is shown
The correct relation between I, 1, and I, is (I-moment of
inertia):

(a) I1>I2, (b), (c)I2>I1, (d)I3>I2​

Answer 1

Answer:answer is "c

Explanation:longest side is AC

So the centre of mass of the whole system present most near to AC.' the

Side BC is so small so centre of mass far from it.

Now we know about parllel axis theorem (I=Icm +Md^2)

Here lcm is moment of inertia at centre of mass and (d) is distance of point at which we have to find moment of inertia' and particular I (moment of inertia) of point directly perpotional to d. So BC which is more far from centre of mass have bigger value of d so have large moment of inertia.
