Question

If a force of $2\text{N}$ is applied towards east and another force on $2\text{N}$ is applied towards north simultaneously on a particle, what will be the magnitude of the net force acting on it?

• A. $2\sqrt{3}\text{N}$
• B. $3\sqrt{2}\text{N}$
• C. $2\sqrt{2}\text{N}$
• D. $2\text{N}$

Answer 1

The correct option is C $2\sqrt{2}\text{N}$

Since both forces are acting perpendicular to each other,

$F_{net}=\sqrt{F_1^2+F_2^2}$

$F_{net}=\sqrt{2^2+2^2}\text{N}$
$F_{net}=2\sqrt{2}\text{N}$
