Given that
n = 16 , r = 0.1 m , i = 0.75 A , B= 5 × 10-² T , V= 2 s-¹ , I = ?
M = niA = niπr² = 16×0.75×22/7×(0.1)² =>0.377jT-¹
as v= 1/2π√MB/l where I is the moment of inertia of the coil .
therefore v² = MB/4π²I or I = MB/4π²v² =>
0.377×5×10-²/4×(22/7)²×2²
=> 1.2×10-⁴ Kg- m² .
I hope it will help you .
