Acork has weight mg and density 25% of water’s density. a string is tied around the cork and attached to the bottom of a water-filled container. the cork is totally immersed. express the tension in the string in terms of the cork weight mg.

Explanation:

Given

Density of Cork

Considering V be the volume of Cork

Buoyant Force will be acting Upward and Weight is acting Downward along with T

Since density of water is more than cork therefore Cork will try to escape out of water but due to tension it will not

we can write as

where T=tension

Thus Tension T is

Taking common

kinetic

i'm so sorry if this is wrong i'm only in 6th grade xd

you have to draw the persons position over there
