Problem
An artificial satellite is moving in a circular orbit around the earth with a speed equal to half the magnitude of escape velocity from the surface of earth. R is the radius of earth and g is acceleration due to gravity at the surface of earth. (R=6400 km)
Then the distance of satellite from the surface of earth is
(A) 3200 km
(B) 6400 km
(C) 12800 km
(D) 4800 km
