Question

the cylinders A and B are of the same as for the radius of A is greater than that of B which one will require more force to come into rotation and why​

Answer 1

Answer:

a is the correct information

Answer 2

We can treat cylinders A as hollow and B as solid. For hollow cylinder A,

K²/R²= 1

and,

cylinder B : K²/R²= 1/2

therefore, V (A)= √2gh/(1+1 )= √2gh

V (B)=√2gh/(1+1/2)=√4gh/3

V(B) >V(A)
