P তে উভয় বস্তুর জন্য সৃষ্ট মহাকর্ষীয় বিভব কত? [what is the gravitational potential at point P due to both objects?]

Question

Accepted Answer

$$V = -\frac{GM}{r}$$ P-তে A-এর জন্য বিভব: $$V_A = -\frac{6.7 	imes 10^{-11} 	imes 8000}{0.20} = -\frac{5.36 	imes 10^{-7}}{0.20} = -2.68 	imes 10^{-6} \ 	ext{J/kg}$$ P-তে B-এর জন্য বিভব: $$V_B = -\frac{6.7 	imes 10^{-11} 	imes 6000}{0.15} = -\frac{4.02 	imes 10^{-7}}{0.15} = -2.68 	imes 10^{-6} \ 	ext{J/kg}$$ মোট বিভব: $$V_P = V_A + V_B = -2.68 	imes 10^{-6} + (-2.68 	imes 10^{-6}) = -5.36 	imes 10^{-6} \ 	ext{J/kg}$$ $$V = -\frac{GM}{r}$$ Potential at P due to A: $$V_A = -\frac{6.7 	imes 10^{-11} 	imes 8000}{0.20} = -\frac{5.36 	imes 10^{-7}}{0.20} = -2.68 	imes 10^{-6} \ 	ext{J/kg}$$ Potential at P due to B: $$V_B = -\frac{6.7 	imes 10^{-11} 	imes 6000}{0.15} = -\frac{4.02 	imes 10^{-7}}{0.15} = -2.68 	imes 10^{-6} \ 	ext{J/kg}$$ Total potential: $$V_P = V_A + V_B = -2.68 	imes 10^{-6} + (-2.68 	imes 10^{-6}) = -5.36 	imes 10^{-6} \ 	ext{J/kg}$$
