What mass of lead will weigh as much as ...

What mass of lead will weigh as much as 8 gm of iron when both are immersed in water ? (given specific gravities of iron and lead are 8 and 11 respectively).

A

1

B

Between 0 and 1

C

0

D

`gt 1`

Text Solution

Verified by Experts

The correct Answer is:
D
`rho=M/V implies rho prop 1/V`
`(rho_l)/(rho_I)=(V_I)/(V_l)` as `rho_l gt rho_I implies V_I gt V_l`
`(W_1)/(W_2) gt 1` As `(V_1 rho_w g)/(V_l rho_w g) gt 1`
