If `v_(0)` orbital velocity of a surface to a circular orbital close in the earth's surface and `v_(1)` scape velocity from earth then relation between the two is

A

`V_(0)=V_(e)`

B

`V_(e)=sqrt(2)V_(0)`

C

`V_(e)=sqrt(3)V_(0)`

D

`V_(e)=2V_(0)`

Text Solution

Verified by Experts

The correct Answer is:
B
Least count
`L.C.=0.02mm`
`e=-(50-44)(0.02)=0.12mm`
`therefore` true reading `=5+0.02xx25+0.12mm=5.62mm`
