Question

Block a of mass 10 kg connected ti hollow block



b.Floats in water spring contanat .Compression in te sorin us

Answer 1

Answer: density of water= 1*10^3

Density= mass /volume

Volume=1*10^3/10=100

Spring compression

K=mg/x

X=mg/k

X=10*10/500=1/5

X 1/5=100

X=20

Answer 2

I will tell you all the formulas related to your question.

Explanation:

Mass Of the block is given which is 10 kg.

Gravitational acceleration 'g' = 9.8 m/s.

                 Force,       'F' = m x g

                               ⇒  F = 10 x 9.8

                               ⇒  F = 98 N

Spring force is equal to the product of spring coefficient and the deflection or compression.

                  Spring force,            

                                       ⇒  F = kx

          k = spring constant

          x = deflection
