Question

a body weight 200 gf in air and 1800 gf when completely immersed in water calculate the loss of weight of body upthrust on the body ​

Answer 1

Answer:

Typing mistake/wrong question

Explanation:

The body weighs 200 gf in air and 1800 gf in water.

The question is wrong because the weight should decrease but it increases on the other hand.

Then the upthrust of water will be negative which is not valid.

So assuming it to be typing mistake and 180 gf :

Upthrust = weight in air - weight in water

⇒ U = 200 gf - 180 gf

⇒ U = 20 gf

Answer 2

Given,

Weight of the body in air = 200 gf

Weight of the body in water = 190 gf

i) Loss in weight of the body = 200gf - 190gf

=> 10 gf........ (ans)

ii) Upthrust on the body = loss in weight

=> 10 gf....... (ans)
