The magnitude of the gravitational attraction between the earth and a particle is 40N. If the mass of the particle is 4kg. Calculate the magnitude of the gravitational field intensity of the earth on the particle
-
A.
10.0N kg-1 -
B.
12.6N kg-1 -
C.
25.0N kg-1 -
D.
160.0N kg-1
Correct Answer: Option A
Explanation
g = (frac{f}{m} = frac{40}{4} = 10N kg^{-1})
