Detailed Solution

Concept: Kg are commonly used as a unit of mass measurement. When a body is said to weigh 2 kg, it actually means 2 kilogrammes. In terms of how weight is defined, weight is the force exerted on a body at the surface of the earth. It is a function of mass times the acceleration brought on by gravity (g). Newton (N) is its unit.
The force operating on a body weighing 1 kg at the surface of the earth is hence referred to as 1 kg Wt. How accurate is that, then? We may get the quantity in newtons by dividing 1 kg by the gravitational acceleration (g).
In the case at hand, the force acting on the body is 9.8N per 1 Kg Wt.
The force exerted on an object is therefore defined as mass times acceleration by Newton's alternative law.
F = ma
⇒ a = Fm = 9.89.8
∴ a = 1 m/ s2
So, the answer to the question is option(1) 1 m/s2.
Hence, the correct option is 1.
