The common error is to think that pressure at
0.4h above the surface of the reservoir of
mercury is 0.4 times the atmospheric pressure.
The pressure at p is caused by the weight of mercury above point P. Thus preesure at P
is equal to : 0.6x 100000 = 60000 Pa

Bcoz when glass Q is painted with light blue we are still able to see the mark , that means its still translucent. When glass R is painted with black, we are not able to see as black is an opaque color. This what the logic meant for. So, option B is correct
Ans 6:

All of them were made of glass. So if P was left as it is without painting wouldn't it be transparent??
Ans 7:
Class : Class 6
Option A can also be a correct answer because the transparency of the glass is not mentioned. It can be translucent or transparent as well.

Falguni and Tanmay , the C option is correct as R is opaque but the question is through which slide can we see the X mark clearly or partially and we can't see through because as you said R is opaque . Answer D is not correct either because colour affects the transparency of the slide. Answer A is not correct because P is transparent not translucent. That leaves us with Option B which is correct as Q is translucent and the students can see the X partially through it . Hope this explanation helps you clear all your doubts about this question.💜💜💜Oh and by the way completely not related to the question who else is an army ( BTS fans ) ?
