A dry soil sample has void ratio 0.4. Without any change in void ratio, water is added to the sample so that its degree of saturation is 35%. Considering the unit weight of water as 10 kN/m3, If sp. gravity of soil is 2.65, then difference in unit weight of the sample will be:
1
1.4 kN/m3
2
1 kN/m3
3
1.35 kN/m3
4
0.95 kN/m3
