Two objects of masses 80kg and 50kg are separated by a distance of 0.2m. If the gravitational constant is 6.6 x 10-11Nm
- 4.9 x 10-9N
- 1.3 x 10-6N
- 6.6 x 10-8N
-
6.6 x 10-6N
- 2.6 x 10-9N
The correct answer is: D
Explanation
F = \(\frac{Gm_1m_2}{r^2} = \frac{6.6 \times 10^{-11} \times 80 \times 50}{0.2 \times 0.2}\)= 6.6 x 10-6N
