Weigh of a body can be measured using a spring balance, it differs from place to place because of variation in ______?

جسم کا وزن موسم بہار کے توازن کا استعمال کرتے ہوئے ناپا جا سکتا ہے، یہ ______ میں مختلف ہونے کی وجہ سے جگہ جگہ مختلف ہوتا ہے؟
Explanation

The weight of a body is the force exerted on it by gravity.

It depends on the gravitational pull of the planet or moon it is on.

Since the gravitational pull varies from place to place (it is stronger near the surface of the Earth than on a mountain, and weaker on the Moon than on the Earth), the weight of a body also varies.
