Q:

# If a body weighs 12N on the surface of the earth, how much will it weigh on the surface of the moon where acceleration due to gravity is only one-sixth of that on earth's surface?

 A) 12N B) 2N C) 10N D) 6N

Explanation:

Weight is mass x g. Since mass is constant and g is only $16th$of that on the earth. The weight on the moon is only $16th$ of that on the earth.

Therefore 2N i.e (b) is the answer.
