A positively charge sphere of radius r0 ...

A positively charge sphere of radius `r_0` carries a volume charge density `rho`. A spherical cavity of radius `r_0//2` is then scooped out and left empty. `C_1` is the center of the sphere and `C_2` that of the cavity. What is the direction and magnitude of the electric field at point B?

A

`(17pr_(0))/ (54epsilon_(0))"left"`

B

`(17pr_(0))/ (54epsilon_(0))"right"`

C

`(pr_(0))/ (6epsilon_(0))"left"`

D
