एक पिंड को पृथ्वी की सतह से ऊपर की ओर पलायन वेग (escape velocity) के बराबर वेग से लंबवत प्रक्षेपित किया जाता है। पृथ्वी की सतह से h ऊंचाई तक पहुंचने में इसके द्वारा लिया गया समय किसके द्वारा दिया जाता है?
- 113√[2Re/g] × [(1 + h/Re)3/2 - 1]✓
- 213√[Re/(2g)] × [(1 + h/Re)3/2 - 1]
- 3√[2Re/g] × [(1 + h/Re)3/2 - 1]
- 4√[Re/(2g)] × [(1 + h/Re)2 - 1]
सही उत्तर देखें
13√[2Re/g] × [(1 + h/Re)3/2 - 1]
