A raft of wood (density`=600kg//m^(3))` of mass `120 kg` floats in water. How much weight can be put on the raft to make it just sink?

A

120 kg

B

200 kg

C

40 kg

D

80 kg

Text Solution

Verified by Experts

The correct Answer is:
D
`V=("mass")/("density")=(120)/(600)=(1)/(5)`
`(x+120)g=(1)/(5)xx1000xxg rArr x=80kg`
