Column I
Column II
(i) Net force on cylinder liquid -1
(a) Zero
(ii) 
(b) W
(iii) Net force on cylinder from liquid -2

(d) None of these |
- i. → d; ii. → c; iii. → a; iv. → b
- i. → d; ii. → b,c; iii. → d; iv. → d
- i. → b; ii. → c; iii. → a; iv. → d
- i. → c; ii. → b,c; iii. → a; iv. → d
The correct answer is: i. → d; ii. → b,c; iii. → d; iv. → d
upthrust
= weight of cylinder in equilibrium or floating condition.
From liquid-1, horizontal pair of forces cancel out.
So, net force = 0
