A block of steel of size 5 cm x 5 cm x 5 cm is weighed in water. If the relative density of steel is 7, its apparent weight is:

A

`6 xx 5 xx 5 xx 5` g

B

`4xx4xx4xx7g`

C

`4xx4xx4xx6g`

D

`5xx5xx5xx7g`

Text Solution

Verified by Experts

The correct Answer is:
A
Apparent weight = weight in air - wt. of water displaced
`=vp_(5)g-vp_(w)g`
`=(Vp_(s)-vp_(w))g`
`=[5xx5xx5xx7-5xx5xx5xx1]g`
`=5xx5xx5xx6g`
Hence correct choice is (a).
