Let the normal force at the contact between rod and cylinder is N1, and between inclined plane and cylinder is N2. Now, suppose m is doubles to 2m, and as a result N1 & N2 changes to N1' & N2' respectively. (suppose friction is still sufficient to keep cylinder at rest ) Choose the correct option(*)

(A) N1' = 2N1

(B) N1' = 4/3N1

(C) N2' = 4/3N2

(D) N2' = 2N2
