Two spherical , nonconducting and very tin shells of uniformly distributed positive charge `Q` and radius d are located a distance ` 10d` from each other . A positive point charge q is placed inside one of the shells at a distance ` d//2` from the center, on the line connecting the centers of the two shells , as shown in the figure, What is the net force on the charge `q` ? .

Options

A. ` ( q Q ) /( 361 pi epsi _ 0 d ^ 2) ` to the left
B. ` ( q Q ) /( 361 pi epsi _ 0 d ^ 2 ) ` to the right
C. ` (362 q Q ) / ( 361 pi epsi _ 0 d ^2 ) ` to the left
D. ` (360 q Q ) /( 361 pi epsi _ 0 d ^ 2 ) ` to the right
