An orbiting satellite will escape if

A

its speed is increased by `41%`

B

its speed in the orbit is increased to

C

its kinetic energy is doubled

D

if it stops moving in the orbit

Text Solution

Verified by Experts

The correct Answer is:
A, C
`V_(e)=sqrt((2GM)/(r ))`, `v_(0)=sqrt((GM)/(r ))`,
`(v_(e )-v_(0))/(v_(o))=(sqrt(2)-1)/(1)=0.41` or `41%`
`(KE_(2))/(KE_(1))=((v_(o))/(v_(0)))^(2)=2`
`implies KE` is doubled
