Question

Two forces 3 N each act on a body at an angle of 120° to each other.
The magnitude of the resultant force acting on the body in Newton is​

Answer 1

Answer:

3N of resultant force will be acting on the body.

Explanation:

• In context to the given question, we have to find the resultant force acting on the body.
• Given,

Two Forces = 3N

θ ( angle between two forces) = 120°

solution;

Let the two forces be 'A' and 'B'

A = B = 3N

WE know that,

Resultant force = √(A² + B² + 2 AB cosθ)

Resultant force = √(3² + 3² + 2 (3)(3) cos120°)

Resultant force = √(9 + 9+ 2 (9)(-0.5))

Resultant force = √(9+9-9)

Resultant force = √(9)

Resultant force = 3N

∴ 3N of resultant force will be acting on the body.
