A pressure of $10\ kPa$ acts on an area of $0.3\ m^2$. The force acting on the area will be:
$(a)$. 3000 N
$(b)$. 30 N
$(c)$. 3 N
$(d)$. 300 N

Here given, pressure $P=10\ kPa=10\times10^3\ Pa$

Area $A=0.3\ m^2$

Let $F$ be the force acting upon the area.

Now, on using $P=\frac{F}{A}$

Or $10\times10^3=\frac{F}{0.3}$

Or $F=0.3\times10\times10^3$

Or $F=3000\ N$

So, option (a) is correct.
