Question:
Radiation from the Sun reaching Earth (just outside the atmosphere) has an intensity of 1.4kW/m2.
(a) Assuming that Earth (and its atmosphere) behaves like a flat disk perpendicular to the Sun's rays and that all the incident energy is absorbed; calculate the force on Earth due to radiation pressure.
(b) For comparison, calculate the force due to the Sun's gravitational attraction.
Step by Step Answer:
a The radiation pressure produces a force equ...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
