A force F = 8i -6j -10k newton produces acceleration of 1 ms-2 in a body. The mass of the body is:
Correct answer: B. 10√2kg
- A. 10kg
- B. 10√2kg
- C. 10√3kg
- D. 200kg
Explanation
Magnitude of force |F| = √(8² + (−6)² + (−10)²) = √(64+36+100) = √200 = 10√2 N. With a = 1 m/s², mass m = |F|/a = 10√2 kg.

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.
