Which one of the following plots represent the variation of gravitational field on a particle with distance r due to a thin spherical shell of radius R? (r is measured from the centre of the spherical shell)

Which one of the following plots represent the variation of gravitatio

1.	Which one of the following plots represent the variation of gravitational field on a particle with distance r due to a thin spherical shell of radius R? (r is measured from the centre of the spherical shell)
Answer» Solution : `implies` Gravitational field INTENSITY at DISTANCE R from the centre of spherical shell of radius R `I= (GM)/r^2 ` (If `r GT R` ) At the surface of shellr = R `:. F = (GM)/R^2` For INSIDE the shell ` r lt R` F=0
