A satellite revolving round the earth in a circular orbit with orbital velocity `v_(0)`. It has kinetic energy E. The additional kinetic energy required to be given to it so that it esscapes from the earth isA. 4 EB. 3 EC. 2 ED. E |

Answer» Correct Answer - d `(E_(2))/(E_(1))=((1)/(2)mv_(e)^())/((1)/(2)mv_(e)^(2))=((2GM)/(R))/((GM)/(R))` `(E_(1))/(E_(1))-1=2-1=1` `E_(2)-E_(1)=E` `DeltaE=E` |
