What is the gravitational field strength on the surface of the Earth? (G = 6.67 × 10^-11 N m²/kg², the mass of the Earth is 5.98 × 10²⁴ kg, and the radius of the Earth is 6.38 × 10⁶ m.) A) 3.40 N/kg. B) 6.20 N/kg. C) 9.80 N/kg. D) 10.1 N/kg. E) 20.3 N/kg.

Question

Quizplus · Accepted Answer

The gravitational field strength on the surface of the Earth can be calculated using the formula,
g = G * (M / R^2), where
g = gravitational field strength
G = universal gravitational constant
M = mass of the Earth
R = radius of the Earth

Substituting the given values, we get
g = 6.67 × 10^-11 * (5.98 × 10^24) / (6.38 × 10^6)^2
g = 9.80 N/kg

Therefore, the best choice is C, 9.80 N/kg.
