Question

figure shows a container filled with a liquid of density rho Four Points a b c and d lie on diametrically opposite of a circle as shown. A and c lie on vertical line in points p and D lie on horizontal line the incorrect statement is VIP BP cpdr absolute pressure at the respective.

Answer 1

Point at same height have same pressure points with heigh difference say 'h' will have difference of pgh
Let radius of circle is r
Pa=Po+hpg
PB=PD=Po+(h+r)pg
Pc=Po+(h+2r)pg
Then,
Pc+Pa=(Po+(h+2r)pg)-(Po+hpg)
=Po+hpg+2rpg+Po+hpg
=2(Po+(h+r)pg)
Pc+Pa/2=Po+(h+r)pg
Pc+Pa/2=PB=PD
That is why option 1,2,4 gives correct statement but incorrect statement is 3
