Question

The value of the gravitational constant (G) determined through the Cavendish balance experiment is approximately:

Options

• 6.67 × 10⁻⁸ N m²/kg²

• 6.67 × 10⁻¹¹ N m²/kg²

• 6.67 × 10⁻¹³ N m²/kg²

• 6.67 × 10⁻⁹ N m²/kg²

Answer 1

6.67 × 10⁻¹¹ N m²/kg²

Explanation:

The gravitational constant is G = 6.67 × 10⁻¹¹ N m²/kg², which is the fundamental value measured using the Cavendish balance method.
