Explanation:
Detailed explanation-1: -At the Earth’s surface, the field strength is about 10 N kg-1.
Detailed explanation-2: -You actually exert a gravitational force on the Earth, but because your mass is many times smaller than the Earth’s mass, your pull is much less than the Earth’s. Gravity is measured as how fast objects accelerate towards each other. The average gravitational pull of the Earth is 9.8 meters per second squared (m/s2).
Detailed explanation-3: -What is the gravitational field strength on Earth? The gravitational field strength on Earth is 9.81m/s2 or N/kg.
