Two identical satellites are at R and 7R away from earth surface, the wrong statement is (R = Radius of earth)

Orbital radius of satellites r1=R+R=2R                                                    r2=R+7R=8R                    U1=−GMmr1 and U2=−GMmr2 and U1U2=r2r1=8R2R=4∵U∝1r K1=GMm2r1 and K2=GMm2r2and K1K2=r2r1=8R2R=4∵K∝1r E1=GMm2r1 and E2=GMm2r2and E1E2=r2r1=8R2R=4∵E∝1r ∴U1U2=K1K2=E1E2=4
