c)Mass of an object is 20 kg. Find its weight on the earth. What will be its weight when measured on the surface of the moon?

Answer 1

Explanation:

Newton's law of universal gravitation. Newton's law of gravitation, statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them.

Gravitation, Matter, & Light. All interactions in the Universe are governed by four fundamental forces. On the large scale, the forces of Gravitation and Electromagetism rule, while the Strong and Weak Forces dominate the microscopic realm of the atomic nucleus.

Weight on earth is 196 Newton ( N ). Since , weight on moon is 1/6 weight on earth. Therefore , weight on moon is 32.6 Newton ( N ).
