A thin spherical shell having uniform density is cut in two parts by a plane and kept separated. The point A is the center of the plane section of the first partand B of the second part. Show that the gravitational field at A due to the first part is equal in magnitude to the gravitational field at B due to the second part. (This is from HC Verma)

33Consider when they are just separated Gravitational Field at the point A(B will coincide with it when 2 parts just touching) will be zero.
Now 4 field at that point to be zero Field at that point due 1st part and due 2 second part are in opposite directions so must be equal in magnitude.
So when separated they will have equal field due 2 them at their points(now separated)
11hey... thanks ..
I thought no one remmbers my doubt!!
The moderators were busy with something else only :)
