Question

The resultant of two forces each equal to p and acting at right angles is:

Answer 1

is equal to either of thes forces

Answer 2

Answer:

$\text{The resultant force is }\sqrt2p$  

Step-by-step explanation:

Given that the two forces each equal to p and acting at right angles.

we have to find the resultant of these two forces

Magnitude of two forces=p

The resultant of two forces can be calculated by the formula

$R=\sqrt{A^2+B^2+2AB\cos\theta}$

$=\sqrt{p^2+p^2+2(p)(p)\cos 90^{\circ}}$

$=\sqrt{2p^2}=\sqrt2p$    [as cos 90=0]

which is required resultant force.
