[amp_mcq option1=”1 kg. wt” option2=”9.81 kg. wt” option3=”981 dyne” option4=”$$\frac{1}{{9.81}}$$ kg. wt” correct=”option1″]
The correct answer is A. 1 kg. wt.
One Newton is the force required to accelerate a mass of one kilogram at a rate of one meter per second squared. In other words, if you apply a force of one Newton to a mass of one kilogram, it will accelerate at a rate of one meter per second squared.
One kilogram weight is the force of gravity on a mass of one kilogram at sea level on Earth. This force is equal to 9.81 Newtons.
One dyne is the force required to accelerate a mass of one gram at a rate of one centimeter per second squared. This is a very small unit of force.
$$\frac{1}{{9.81}}$$ kg. wt is not a valid unit of force.
