A wooden cube floating in water supports a mass 0.2 kg on its top. When the mass is removed the cube rises by 2cm. What is the side legnth of the cube ? Density of water `= 10^3 kg//m^3`

A

10cm

B

20cm

C

15cm

D

25cm

Text Solution

Verified by Experts

The correct Answer is:
A
Weight of body = Weight of water displaced so, `200 xx g= I xx l xx 2 xx 1xxg`
or `l^2 = 100 " or " l = 10 cm`
