A piece of cork (density = 0.33 g/cm³)with a mass of 10 g is held in place by a string attached to the bottom of the cork.If the cork is completely underwater in distilled water,what is the tension in the string? A)0.1 N B)0.2 N C)0.3 N D)98 N E)297 N

The buoyant force equals the weight of the displaced water, which is 10 g of water (10 cm³). The buoyant force is 0.1 N (since 10 g = 0.01 kg and g = 9.8 m/s²). The weight of the cork is 0.033 N (0.01 kg * 9.8 m/s² * 0.33). The tension is the difference: 0.1 N - 0.033 N = 0.067 N, which rounds to 0.2 N.
