Statement -1: A smooth block of mass `2kg` and specific gravity `2.5` is attached with a spring of force constant `k = 100 N//m` and is half dipped in water. If the extension in the spring is 1cm, the force exteted by the bottom of tank on the block is `19N`.
Statement-2 : In the arrangement shown, the buoyant force acting on the block is equal to weight of liquid displaced.

Options

A. Statement I is true, statement II is true and statement II is correct explanation for statement I
B. Statement I is true, statement II is true and statement II is not the correct explanation for statement I
C. Statement I is true, statement II is false.
D. Statement I is false, statement II is true.

Answer

B

Explanation

`f_(B)+kx=mgimpliesf_(B)=20-1=19N`
