A uniformly charged thin spherical shell of radius R carries uniform surface charge denisty of `isgma` per unit area. It is made of two hemispherical shells, held together by presisng them with force F(see figure). F is proportional to

Options

A. `(1)/(epsilon_(0))sigma^(2)R^(2)`
B. `(1)/(epsilon_(0))sigma^(2)R`
C. `(1)/(epsilon_(0))(sigma^(2))/(R)`
D. `(1)/(epsilon_(0))(sigma^(2))/(R^(2))`

Answer

1

Explanation

Pressure =` (sigma^(2))/(2epsilon_(0))` and Force=`(sigma^(2))/(2epsilon_(0))xxpiR^(2)`
