In question it is not 1 kg weight, its 1 kg mass: since unit of weight is Newton and unit of mass is Kg.

So the question should be:

1 kg of mass equals _____ weight?

Answer: Weight = Mass x gravity.

= 1 kg x 9.81 m/s^2.

= 9.81 N (answer B).

Yes friends, the question says to us,
One kg of mass equal to -------- weight?

Answer: Weight = mass x gravity.
= 1kg x 9.81 m/sec^2.
= 9.81 N.

Here give that:

Mass = 1 kg

He wants weight.

So W = 1*9.8 (kg x m/sec^2)
= 9.8 N.

w = mg.
Weight = Mass x Gravity.
where;
Mass = 1 kg.
g = gravity = 9.81 m/sec^2.
w = 9.81N.

w = mg.
where m = 1 kg.
g = gravity = 9.81 m/sec^2.
w = 9.81N.

w = mg where g = 9. 8m/s^2 & m=1kg.

Since w=1*9. 8=9. 8N.

Answer = Mass x Garvity.

1 kg = mass.

Wt = 1*9.8 = 9.8 kg.

Ravi sahu said:   8 years ago
w=mg.
where m= 1 kg.
g =gravity =9.81 m/sec^2.
w=9.81N.

Weight = Mass x Gravity.

1kg = Mass.

Wt = 9.8.

1kg = 1*9.8 = 9.8N.
