An object has a weight (on Earth) of 981 N. What is its mass? (W = m* 9.81 m/s^2)​

Generally spring balance shows the mass of the object as it shows the correct Mass as 10kg if the acceleration is 9.81 m/s2 as they are calibrated in such a way. If it's showing 9.81 kg the gravity (acceleration) is reduced and based on the above assumptions the solution is if (F=ma) 10kg*9.81m/s2=98.1N is shown as 10 kg then what newton is shown as 9.81 kg . The equation is written as 98.1/x=10/9.81. The solution is the force exerted is x=96.236 N . Therefore (F=ma) a=96.236/10 kg (mass constant) is equal to 9.62m/s2 (the gravity at this place)
