The force which produces acceleration of 1m/sec2 in a body of mass 1 Kg is equal to
Correct answer: B. One Newton
- A. One dyne
- B. One Newton
- C. 10 Kg
- D. 10 dyne
Explanation
According to Newton's Second Law of Motion, force is calculated as the product of mass and acceleration (F = ma). With a mass of 1 kg and an acceleration of 1 m/s², the force required is 1 Newton, which is the SI unit for force. Option A (One dyne) is incorrect because dyne is a smaller unit of force in the centimeter-gram-second system. Option C (10 Kg) is incorrect because kilogram is a unit of mass, not force. Option D (10 dyne) is incorrect as it represents a much smaller force than 1 Newton.

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.
