Question

A T ***** is formed by two identical rods A & B each of mass m & length L in the XY plane as shown. Its moment of inertia about axis coinciding with A is :–

(a) 2mL2/3

(b) mL2/12

(c) mL2/6

(d) of these

Answer 1

Correct Option (b) mL2/12

Explanation:

I = I1 + I1 = I = 0 + ML2/12 = I = ML2/12u200bu200bu200bu200bu200bu200bu200b
