A satellite orbiting close to earth surface will escape, if

A

its speed is increased by `41.4%`

B

its speed in the orbit `(sqrt(1.5))` times of its initial value

C

its K.E. is 1.5 times

D

it stops moving in the orbit

Text Solution

Verified by Experts

The correct Answer is:
a
`v_(e)=sqrt2v_(c)`
`(v_(e))/(v_(c))=1.414`
`(v_(e)-v_(c))/(v_(e))=41.4%`
