Share 1 FOLLOW 1 student-name Neha Sarin answered this 409 helpful votes in Physics, Class XII-Science we know that orbital velocity vo= √(g.r) escape velocity ve = √(2g.r) thus, the increase in velocity WOULD be dv = ve - vo = √(2g.r) - √(g.r) or dv = (√2 - √1).√(g.r) so, dv = 0.414√(g.r) now, the percentage increse would be % dv = [(ve - vo) / vo ] x 100 = (dv / vo) x 100 or = [0.414√(g.r) / √(g.r)] x 100 so, we get % dv = 0.414 x 100 = 41.4% |
