Question

Consider a uniform spherical charge distribution
of radius R₁ centred at the origin O. In this
distribution, a spherical cavity of radius R₂,
centred at P with distance OP = a = R₁ – R₂ (see
figure) is made. If the electric field inside the
cavity at position ￫r is ￫E(￫r), then the correct statement(s) is(are)
(A)￫E is uniform, its magnitude is independent of R2 but its direction depends on ￫r
(B)￫E is uniform, its magnitude depends on R2 and its direction depends on ￫r
(C)￫E is uniform, its magnitude is independent of a but its direction depends on ￫a
(D)￫E is uniform and both its magnitude and direction depend on ￫a
