Answer 1

Explanation:

Electric field due to a hollow spherical conductor is governed by equations E = 0, for r < R   …(i)

and E = `"Q"/(4piepsilon_0"r"^2)` for r ≥ R ….(ii)

i.e. inside the conductor, electric field will be zero and outside the conductor it will vary according to E oc `1/"r"^2`.
