JEE Main 2025 Physics question
A satellite of mass 1000 kg is launched to revolve around the earth in an orbit at a height of 270 km from the earth's surface. Kinetic energy of the satellite in this orbit is × 10¹⁰ J. (Mass of earth = 6 × 10²⁴ kg, Radius of earth = 6.4 × 10⁶ m, Gravitational constant = 6.67 × 10⁻¹¹ Nm²kg⁻²)
Answer: 3
Solution
with km; computing gives J.
