Q.A non-conducting solid sphere has volume charge density that varies as ρ = ρ₀ r, where ρ₀ is a constant and r is distance from centre. Find out electric field intensities at r < R and r ≥ R (JEE Main 2018)

For r < R: (ρ₀ r²)/(3 ε₀); for r ≥ R: (ρ₀ R³)/(3 ε₀ r²)

For r < R: (ρ₀ r)/(3 ε₀); for r ≥ R: (ρ₀ R⁴)/(3 ε₀ r³)

For r < R: (ρ₀ r)/(ε₀); for r ≥ R: (ρ₀ R³)/(ε₀ r²)

For r < R: (ρ₀ r²)/(ε₀); for r ≥ R: (ρ₀ R³)/(ε₀ r²)

The correct solution involves applying the fundamental concept to derive the final value step by step...
