Question

A particle is to be placed in turn, outside four objects, each of mass m:(1) a large uniform solid sphere, (2) a large uniform spherical shell, (3) a small uniform solid sphere,
and (4) a small uniform shell. In each situation, the distance between the particle and the center of the object is d. Rank the objects according to the magnitude of the gravitational force they exert on the particle, greatest first.​

Answer 1

Answer:

Please find below the solution to the asked query:

the gravitational field outside a solid sphere  or a hollow shell of same mass mGmr2so in all cases For a large uniform spherical shell , large uniform solid sphere or small shell or even a small uniform solid sphereeach of mass m will exert an equal force on the object kept outside it.the force on the mass will be F = GmMr2(M Is the mass of the particle outside)the gravitational field outside a solid sphere  or a hollow shell of same mass mGmr2so in all cases For a large uniform spherical shell , large uniform solid sphere or small shell or even a small uniform solid sphereeach of mass m will exert an equal force on the object kept outside it.the force on the mass will be F = GmMr2(M Is the mass of the particle outside)
