Option A will be the correct Answer.

Karan said:   9 years ago
Option A will be the correct answer. Because the pressure, P = π * W * w2 * r2/4g.

Vinash ka devta said:   9 years ago
C is right.

Because, w=area * height.

Ahlawat said:   8 years ago
Option A is correct, w is not volume it is a specific weight which is density * s.g.

Minesh Rathore said:   8 years ago
A is correct because P = (density * w2 * r2)/2.

Ajaypal said:   8 years ago
Option C is correct because " Total Pressure "(and not pressure) has been asked which means Force on Area [&pie;*r^2].

So, Total pressure = Pressure * Area.
And hence Total pressure is proportional to r^4.

@Ajaypal.

If total pressure =pressure*area.
The Unit will become as N/mm4.

It is πww^2r^4/4g.

Thanks @Ajaypal.

@Ajaypal.

Here m^2 and m^2 will be cancelled. It should not be multiply.
