R_(1) and R_2 (R_(1) lt R_(2))are radii of two isolated sphere A and B respectively having same surface density. Hence the intensity of electric field at the surface is ......... |

Answer» more on SPHERE A `therefore`ELECTRIC FIELD on the surface, `E = (kQ)/R^(2)` But `sigma =Q/(4piR^(2)) rArr Q = 4piR^(2)sigma` and `k=1/(4piepsilon_(0))` `therefore E = sigma/epsilon_(0)` Hence the electric field does not depend on radius or area of the surface. Therefore, the intensity of electric field is same on both spheres. |
