Question

Match the Column I with Column II and mark the correct choice from the given codes.

Column I		Column II
i	For translational equilibrium	p	$MK^{2}$
ii	For rotational equilibrium	q	Angular acceleration
iii	Moment of inertia of a body	r	$\sum \vec{F}=0$
iv	Torque is required to produce	s	$\sum \vec{\tau}=0$

• A. (i) - (p), (ii) - (q), (iii) - (r), (iv) - (s)
• B. (i) - (q), (ii) - (r), (iii) - (s), (iv) - (p)
• C. (i) - (r), (ii) - (q), (iii) - (p), (iv) - (s)
• D. (i) - (r), (ii) - (s), (iii) - (p), (iv) - (q)

Answer 1

Answer: (D)

For translational equilibrium, $\sum \vec{F}=0$
(i) $- r$
For rotational equilibrium, $\sum \vec{\tau}=0$
(ii) $- s$
Moment of inertia of a body $=M k^{2}$
(iii) $- p$
Torque is required to produce angular acceleration.
(iv) - q
