1.	An artificial satellite moving in a circular orbit around the earth has a total (kinetic + potential) energy E_(0). Its potential energy and kinetic energy respectively are
Answer» `2E_(0) and -2E_(0)` `-2E_(0) and E_(0)` `2E_(0) and -E_(0)` `-2E_(0) and -E_(0)` Solution :`because` Total energy, `E_(0)=-(GMM)/(2r)` Potential energy, `U=-(GMm)/(R)=2E_(0)` KINETIC energy, `K=+(GMm)/(2r)=-E_(0)`.
