Two rods of same material and length have their electric resistance in...
Explanation:

Electric Resistance:
- The electric resistance of a material is dependent on its resistivity and length.
- Given that the two rods have the same material and length, their resistances are in a ratio of 1:2.

Effect of Water:
- When the rods are dipped in water, the resistance of a material decreases due to the presence of water which is a good conductor of electricity.
- The decrease in resistance causes a decrease in the weight of the rods due to the loss of electrons.

Loss of Weight:
- Since the resistance of rod A is lower compared to rod B, the decrease in weight due to the loss of electrons will be higher for rod A.
- Therefore, option 'A' stating that rod A has more loss of weight is the correct statement.
In conclusion, when the two rods of the same material and length are dipped in water, the rod with lower electric resistance will experience a higher loss of weight due to the increased flow of electrons in the presence of water.
