Q. If gravitational force on a body of mass 1.5 kg at point is 45N, then the intensity of the gravitational field at that point is
A) $67.5\ N\ kg^{- 1}$
B) $45\ N\ kg^{- 1}$
C) $30\ N\ kg^{- 1}$
D) $15\ N\ kg^{- 1}$
Explanation
(c) $F = mI$
$\therefore I = \frac{F}{m} = \frac{45}{1.5} = 30N\ kg^{- 1}$
