What will happen if the height of an orbit of a satellite from surface of earth is increased?
Correct answer: C. Time period increases
- A. Speed increases
- B. Angular velocity increases
- C. Time period increases
- D. Gravitational acceleration increases
Explanation
The time period (orbital period) of a satellite increases when the height of its orbit from the Earth's surface is increased. The time taken to complete one orbit becomes longer as the satellite moves farther from the Earth.

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
