Two rods of same material and length have their electric resistance in ratio I : 2. When both rods are dipped in water, the correct statement will be

R=ρ lA ⇒ R1R2 =  A2A1ρ, L  constant⇒ A2A1 =  R2R1=2Now, when a body dipped in water, loss of weight=VσLg=ALσLgSo, Loss  of  weight1Loss  of  weight2 =A1A2=2;  so A has more loss of weight.
