Both 1and 2 of c

Answer 1

Answer:

Relative Density Of Body = weight of body in air/Upthrust due to water

Wair = 200gf

Wwater = 150

RD = 200/200-150

RD = 200/50

RD = 4

2)

In 2nd Question density is mentioned how can we find

Fup = W air - W liquid

W liquid = Wa - Fup

WL = 200 - Fup

Fup not mention
