use the equation P=hdg since the liquids are in equilibrium the pressure of air (since it is open) on both of them is equal

so P/hg = d

for P p/2xg
for Q p/xg

now divide P by Q to get 0.5
THANKYOU SO VERY MUCH!!
:D

answer is A because,
imagine the wave moving what will be the next position of P after moving for a while? (note that this is a transverse not stationary wave)
the position will be downwards and Q will take P "position" and be stationary

Point Q is momentarily stationary.
between trough and crest, motion of particles is downwards. So Q downwards.

Option A.
ummm i m slightly confused here: u said Q is downwards then u selected option A which says Q is stationary.....pleaaasee elaborate....thanx so much for helping:)

Use your common sense, too. I said any particle b/w a trough and crest is downwards.

sorry i still don't get it:( i mean the wave is moving from left to right so how can the next position of P be downwards???:cry:
