The force of attraction due to a hollow speheical shell of mass M radius R and and unifor density on a point mass m situdated inside it is

A

`(GmN)/(r^(2))`

B

`(GmM)/(R^(2))`

C

zero

D

data insufficient

Text Solution

Verified by Experts

The correct Answer is:
C
No field exist inside the spherical shell so net resultant force at point P is

`rarr |F_(p)(net)|=zero`
