vikas askiitian expert · Answer

I = mr 2 particles are placed at 1,2,3........& so on I 1 = m 1 r 1 2 , I 2 = m 2 r 2 2 & so on ........ I = I 1 + I 2 + I 3 ............... n I = 10 -7 [(1)(1) 2 + 2(2) 2 + (3)(3 2 ) ...................n] ( putting m in grams & r in m) I = 10 -7 [1 3 + 2 3 + 3 3 ..........n] I = [n(n+1)/2 ] 2 *10 -7 kg-m 2 here n is the number of particles ....
