(a) प्यारासूट प्रयोग गरेर चन्द्रमामा सुरक्षित अवतरण गर्न सम्भव छैन, किन ?
Why is it not possible to land safely on the Moon using a parachute?
(b) दुईआँटा आकाशीय पिण्डहरू क्रमश : \(2\times10^{30}\) kg तथा \(1.9\times10^{27}\) kg रहेको छ । यदि तिनीहरूको केन्द्रीबिचको दूरी \(1.8\times10^{8}\) km भए यी दुई पिण्डहरूबिचको गुरुत्वाकर्षण बल हिसाब गर्नुहोस् । यदि दुरीलाई \(3.6\times10^{8}\) km बनाउँदा गुरुत्वाकर्षण बलमा के भिन्नता आउँछ ?
Mass of the two heavenly bodies are \(2\times10^{30}\) kg and \(1.9\times10^{27}\) kg respectively. If the distance between their centers is \(1.8\times10^{8}\) km. Calculate the gravitational force between them. What would be the force of attraction if the distance between the masses is made \(3.6\times10^{8}\) km.
