Question

In column I, information about the force(s) acting on a body is mentioned, while in Column II information about the motion of a body is given. Match the entries in Column II with the entries in Column I.

List 1	List 2
A single force through centre of mass	Rotational motion
Equal and opposite forces separated by non-zero distance	Translational motion
Equal and opposite forces acting at the same point	No motion
A single force not through centre of mass	Centre of mass performs curvilinear motion

• A. D$\to$4,2,1, C$\to$3, B$\to$1, A$\to$ 2
• B. A$\to$4,2, B$\to$3,1, C$\to$1, D$\to$ 2
• C. C$\to$4,2,1, D$\to$3, A$\to$1, B$\to$ 2
• D. B$\to$4,1, A$\to$3,2 C$\to$1, D$\to$ 2

Answer 1

The correct option is A D$\to$4,2,1, C$\to$3, B$\to$1, A$\to$ 2

i. Pure translational motion
ii. Pure rotational motion about centre of mass
iii. No motion as $\sum \overrightarrow{F}=0$ and $\sum \overrightarrow{\tau }=0$
iv. Combined rotational and translational motion.
