Question

its argent plzzz answer.....................

Answer 1

We know,

Gravitational force, $F = G \frac{Mm}{r^2}$

Here,
M = m = 10 kg
r = 50 cm = 50/100 m = 0.5 m
G = 6.674 × 10⁻¹¹ m³ kg⁻¹ s⁻²

∴ F = 6.674 × 10⁻¹¹ × 10 × 10/ (0.5)²

       = 6.674 × 10⁻¹¹ × 10²/ 0.25

       = 6.674/0.25 × 10⁻⁹

       = 26.686 × 10⁻⁹ N/kg

Thus the gravitational force between the two given bodies is 26.686 × 10⁻⁹ N/kg
