Question

Match the difference in level and angle (θ) of line connecting O to A in Column I with the respective options in Column II. (Liquid is ideal in all cases and g = 10 m/s²)

Column I	Column II
(A)	(p) The difference in the vertical height between O and A is 1.25 m
(B)	(q) The difference in the vertical height between O and A is 2.5 m
(C)	(r)  θ = tan-1 (1/2)
(D)	(s)  θ = tan-1 (1/4)
	(t)  θ = tan-1 (5/4)

Answer 1

(A) - p, t ; (B) - p, s ; (C) - q, r ; (D) - q, r
