The orbital velocity of a satellite in a circular orbit close to the earth is v_0 . If the escape velocity of an object projected from the earth be v_e,then the ratio of these two velocities is

The orbital velocity of a satellite in a circular orbit close to the e

1.	The orbital velocity of a satellite in a circular orbit close to the earth is v_0 . If the escape velocity of an object projected from the earth be v_e,then the ratio of these two velocities is
Answer» `1:1` `sqrt(2):1` `sqrt(3):1` `2:1` SOLUTION :`(v_e)/(v_0)= sqrt((2gR)/(sqrt(GR)))=sqrt(2)/1`
