Gravitational field due to a solid sphere

Options

A. remains constant throughout the sphere
B. increase inside the sphere and decreases outside the sphere
C. increases throughout with distance from the center
D. decreases throughout with distance from the centre

Answer

B

Explanation

Graviational field due to a solid sphere
`E(r)=(GM)/(R^(3))r`
`rArrE(r)prop r`, i.e., E(r) increases inside the sphere
`E(r)=(GM)/(r^(2))`
`rArr E(r) prop (1)/(r^(2))`,i.e. E(r) decreases outside the sphere.
