Column II gives certain situations involving two blocks of mass 2 kg and 4 kg. The 4 kg block lies on a smooth horizontal table. There is sufficient friction between both the blocks and there is no relative motion between the blocks in all situation. Horizontal forces act on one or both blocks as shown. Column I gives certain statement related to figures given in column II. Match the statements in column I with the figure in column II.
Column I | Column II |
(a) Magnitude of frictional force is maximum. | (p) |
(b) Magnitude of friction force is least. | (q) |
(c) Friction force on 2 kg block is towards right. | (r) |
(d) Friction force on 2 kg block is towards left. | (s) |

– s, – r, - p, s, - q, r
Sol. The acceleration of two block system for all cases is a = 2 m/s 2
In option (p) the net force on 2 kg block is frictional force
Frictional force on 2 kg block is
f = 2 × 2 = 4N towards right
In option (q) the net force on 4 kg block is frictional force
Frictional force on 4 kg block is
f = 4 × 2 = 8N towards right
In option (r) the net force on 2 kg block is 2 × 2 = 4N
Friction force f on 2 kg block is towards left.
6 – f = 2 × 2 or f = 2N
In option (s) the net force on 2 kg block is ma
= 2 × 2 = 4N towards right.
Friction force on 2 kg block is 12N towards right.
