Earth orbiting satellite will escape if

A

its speed is increased by 41 %

B

its KE is doubled

C

Both (a) and (b) are correct

D

Both (a) and (b) are wrong

Text Solution

Verified by Experts

The correct Answer is:
C
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.

An orbiting satellite will escape if

A satellite is orbiting around the earth in a circular orbit. Its orbital speed is V_(0). A rocket on thrust to the satellite directed radially away from the centre of the earth. The uration of the engine burn is negligible so that it can be considered instantaneous. Due to this thrust a velocity variation DeltaV is imparted to the satellite. Find the minimum value of the ratio (DeltaV)/(V_(0) for which the satellite will escape out of the gravitational field of the earth.

A satellite is revolving round the earth at a height (R/2) from surface of earth in circular orbit. The change ini speed required for the satellite to excape to infinity for the satellite to escape to infinity is: [Take R as radius of earth and M as mass of earth]

A satellite is revolving in a circular orbit at a height h from the earths surface (radius of earth R, h lt lt R ). The minimum increase in its orbital velocity required, so that the satellite could escape from the earths gravitational field, is close to :(Neglect the effect of atmosphere.)

A satellite is revolving in a circular orbit at a height 'h' from the earth's surface (radius of earth R, h ltltR). The minimum increase in its orbital velocity required, So that the satellite could escape from the erth's gravitational field, is close to :(Neglect the effect of atomsphere.)
