Question

a body is acted upon by two forces of magnitude 20N and 30N. calculate the maximum and minimum value of resultant force on a body ​

Answer 1

$\huge\sf\pink{Answer}$

☞ Same Direction = 50 N

☞ Opposite Direction = 10 N

━━━━━━━━━━━━━

$\huge\sf\blue{Given}$

✭ Two forces of 20 N & 30 N acts on a body

━━━━━━━━━━━━━

$\huge\sf\gray{To \:Find}$

◈ The resultant force?

━━━━━━━━━━━━━

$\huge\sf\purple{Steps}$

So here we are just given the Magnitude and not the direction of the force which means that the forces can be either opposite or in the same direction,so

If they are in the same direction

➝ $\sf Resultant \ Force = Sum \ of \ all \ forces$

➝ $\sf Resultant \ Force = 20N + 30N$

➝ $\sf\red{Resultant \ Force = 50N}$

If they are in opposite direction

➳ $\sf Resultant \ Force = Difference \ of \ the \ forces$

Let one force be 30 N and the other be -20N (Opposite direction)

➳ $\sf Resultant \ Force = 30N - 20N$

➳ $\sf\orange{Resultant \ Force = 10N}$
