Type: MCQ-numerical-Hard-Class 11
Convert the gravitational constant G from N m² kg⁻² to cm³ s⁻² g⁻¹ using the given data.
A
6.67 × 10⁻⁸
B
6.67 × 10⁻⁵
C
6.67 × 10⁻¹¹
D
6.67 × 10⁻⁷
Correct Answer
Option A
Detailed Explanation
By converting units: 1 N = 10⁵ dyn, 1 m = 10² cm, 1 kg = 10³ g, G becomes 6.67 × 10⁻¹¹ × 10⁵ × (10²)³ / (10³)² = 6.67 × 10⁻⁸ cm³ s⁻² g⁻¹.
