NEET Physics (general) MCQ Question
Type: MCQ-numerical-Easy-Class 11
Convert the gravitational constant G = 6.67 × 10⁻¹¹ N m² (kg)⁻² to (cm)³ s⁻² g⁻¹.
A
6.67 × 10⁻⁸ (cm)³ s⁻² g⁻¹
B
6.67 × 10⁻⁹ (cm)³ s⁻² g⁻¹
C
6.67 × 10⁻¹³ (cm)³ s⁻² g⁻¹
D
6.67 × 10⁻¹² (cm)³ s⁻² g⁻¹
Correct Answer
Option A
Detailed Explanation
Using the conversion factors: 1 m = 100 cm and 1 kg = 1000 g, G in (cm)³ s⁻² g⁻¹ becomes 6.67 × 10⁻¹¹ × (100)³ × (1000)⁻¹ = 6.67 × 10⁻⁸.
