There are three blocks of masses m ₁= m , m ₂=4 ~m and m ₃= m . If two block system is kept over a smooth hemisphere with two different arrangement one by one as shown in figure (i) & (ii) respectively are connected with massless & inextensible string. In arrangement figure (i), after releasing the system from rest acceleration of blocks is found to be (a= 5 3 2 ) m / s ^2 . In second arrangement block m ₁ & m ₂ are

Correct answer

3

Step-by-step solution

(a) m₁ g = (m₁+m₁ ) a₁ (b) (m₂-m₁ ) g / 2= (m₁+m₂ ) a₂
