To find the force exerted on a perfectly reflecting solid sphere placed in the path of a uniform light beam of intensity \( I \), we can follow these steps: ### Step 1: Understand the Concept of Intensity and Area The intensity \( I \) of the light beam is defined as the power per unit area. The projected area \( A \) of the sphere that faces the light beam is given by: \[ A = \pi R^2 \] where \( R \) is the radius of the sphere. ...
