Two concentric spherical shells have masses M1 and M2 and radii R1 and R2 (R1<R2). What is the force exerted by this system on a particle of mass m if it is at a distance (R1+R2)2 from the centre?
Why this question: It is absolutely important to be well versed with the field due to a solid sphere and a hollow sphere both inside and outside. The concept is extremely important from a JEE standpoint. |
