Question

A plot of gravitational field v/s distance for a thin spherical shell of radius R, follows an exponentially decreasing curve for certain range of distance. The field was determined for

• A. r = 0 to r = R/2
• B. r = 0 to r = R
• C. r = R to r = Infinity
• D. a point on the surface

Answer 1

The correct option is C r = R to r = Infinity

The field is found to be zero from r =0 to r = R and at r =R, the field is maximum
The field starts reducing from r = R to infinity and becomes zero at r = infinity
The correct option is (c)
