ID#5717 HSC Physics 1st MCQ (Jessore 2025)

m₁=1kg, m₂=1kg এবং দূরত্ব 1m হলে ক্রিয়াশীল বলের মান কত?
ক) 6.4 x 10⁶ Nm²kg⁻²
খ) 6 x 10²⁴ Nm²kg⁻²
গ) 6.67 x 10⁻¹¹ Nm²kg⁻²
ঘ) 6.023 x 10²³ Nm²kg⁻²

ব্যাখ্যা

$F = G \frac{m_1 m_2}{r^2} = 6.67 \times 10^{-11} \times \frac{1 \times 1}{1^2} = 6.67 \times 10^{-11} N$।
