Question

four forces are acting on an object. Forces F1=80N and F2=50N towards right of the object and forces F3=100N and F4=20N towards the left of an object. Calculate the resultant force of an object.​

Answer 1

Answer:

10N

Explanation:

it is because:

left forces - 120 = 100 + 20

right forces - 130 = 80 + 50

130 - 120 = 10N

Answer 2

Given

• Four forces act on a body
• F¹ = 80 N → Right
• F² = 50 N → Right
• F³ = 100 N → Left
• F⁴ = 20 N → Left

To Find

• Resultant force

Solution

☯ A body moved in the direction when the force applied is higher and opposing forces cancel each other

• Here we shall assume the left side to be negative and the right side to be positive

━━━━━━━━━━━━━━━━━━━━━━━━━

✭ According to the Question :

➞ Resultant force = Sum of all forces

➞ Resultant force = 80 + 50 + (-100) + (-20)

➞ Resultant force = 80 + 50 - 100 - 20

➞ Resultant force = 130 - 120

➞ Resultant force = 10 N

∴ The body would move towards the right with a force of 10N
