When you dip your hand in the water, you displace a volume of water, causing the liquid level to rise (Statement-2 is true). The force on the bottom of the beaker is the product of the hydrostatic pressure at the bottom and the area: . Since the height increases, the pressure and thus the force also increases (Statement-1 is true). The rise in level is the direct cause for the increased force, so Statement-2 is the correct explanation for Statement-1.
Final Answer: Statement-1 is true, statement-2 is true and statement-2 is correct explanation for statement-1.
