A block A of mass 5kg is placed on another block B of mass 10 kg placed on a horizontal rough surface. Horizontal force F 1 and F 2 acts on block A and B respectively as shown in figure. Coefficient of friction between two blocks is 0.8 while between block B and horizontal surface is 0.2. Let f 1 denote friction force acting on block B due to A and f 2 denote friction force on horizontal surface. Then match the following.
Column I | Column II |
(i) If F1 = 35N, F2 = 0 then f1 | [A] Kinetic |
(ii) If F1 = 50N, F2 = 0 then f2 | [B] Static |
(iii) If F1 = 0, F2 = 30 then f1 | [C] Zero |
(iv) If F1 = 10 N, F2 = 50N then f1 | [D] Towards right |
