Earth orbiting satellite will escape if

Answer»

its speed is increased by 41 %
its KE is doubled
Both (a) and (b) are correct
Both (a) and (b) are wrong

Solution :Escape velocity, `v_(e)=sqrt(2)v_(o)=1414v_(o)` or ORBITAL speed is to be increased by 41 %
Further speed is to INCREASE `sqrt(2)` TIMES and KINETIC enegry is to increase two times.
