Question

If a force of $10\mathrm{N}$ acts on two surfaces having area in the ratio $1:2$, then the ratio of thrusts will be

• A. $1:2$
• B. $2:1$
• C. $3:1$
• D. $1:1$

Answer 1

The correct option is D

$1:1$

Explanation

Thrust is defined as a force acting perpendicular to an object's surface.

So, Thrust = Force

and Force$=10N$

Therefore, Thrust = 10N

Hence, $$\begin{gathered} \frac{{\left(Thrust\right)}_1}{{\left(Thrust\right)}_2}=\frac{10}{10} \\ \frac{{\left(Thrust\right)}_1}{{\left(Thrust\right)}_2}=\frac{1}{1} \end{gathered}$$

The ratio of thrust is $\mathbf{1}\mathbf{:}\mathbf{1}\mathbf{.}$

The correct option is (D).
