Challenge Problems
Push your limits with challenges.
Question 1
If a satellite orbits Earth at a height where the radius of orbit is 2R (twice the Earth's radius), calculate the gravitational force acting on it if its mass is 500 kg.
💡 Hint: Remember, you need to account for the total distance from Earth's center to the satellite.
Question 2
Calculate how much work it would take to move a mass of 100 kg from the Earth's surface to an altitude of 10 km, considering gravitational potential.
💡 Hint: Use the potential energy formula for work done against gravity.
