The universal gravitational constant G has approximate value:
A6.022 \u00d7 10\u00b2\u00b3
B1.6 \u00d7 10\u207b\u00b9\u2079 C
C9.8 N\u00b7m\u00b2/kg\u00b2
D6.67 \u00d7 10\u207b\u00b9\u00b9 N\u00b7m\u00b2/kg\u00b2
Answer & Solution
Correct answer: D. 6.67 \u00d7 10\u207b\u00b9\u00b9 N\u00b7m\u00b2/kg\u00b2
G = 6.67 × 10⁻¹¹ N·m²/kg². It is a universal constant. Note: g = 9.8 m/s² is acceleration due to gravity at Earth's surface (different quantity).
