Question

find the resultant of two forces 5N and 12N acting at right angle

Answer 1

The Resultant Force = $\sf{10N}$

Explanation:

Let,

• $\sf{F_1\:=\:5\:N}$
• $\sf{F_2\:=\:15\:N}$

Resultant Force = $\sf{F_2\:-\:F_1}$($\sf{\:if\:F_2\:>\:F_1}$)

$⟹\sf{15\:-\:5}$

$⟹\sf{10}$

Resultant force of $\sf{10N}$ is acting in the direction of $\sf{F_2}$.

Resultant Force :

When several forces act simultaneously on the same body, then the combined effect of the multiple forces can be represented by a single force, which is termed as 'resultant force'.

• $\sf{F_net\:=\:F_1\:+\:F_2}$
• $\sf{F_net\:=\:F_1\:-\:F_2\:or\:F_2\:-\:F_1}$
