Two forces 3N and 2N are at an angle Ө such that the resultant is R the first force is now increased to 6N, and the resultant becomes 2R. the value of Ө is
Correct answer: B. 600
- A. 300
- B. 600
- C. 900
- D. 1200
Explanation
When two forces are at an angle θ, the resultant (R) can be found using the vector addition:R=F12 +F22 +2F1 F2 cosθ

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
