I had this question before I think was it A or B.
Answer:
is the density of the oil
Explanation:
Given:
- height of oil column,

- oil column height that is more than the water column height in the other arm,

<u>Now from the given it is clear that the height of water column is:</u>



Now according to the pressure balance condition of fluid columns:
Pressure due to water column = Pressure due to oil column



is the density of the oil
In order to see what's going on, let's put them in empty space to get rid of any other influences, and let's also make it a push instead of a pull. / / / The horse pushes on the cart, so it begins accelerating away from him. At the same time, because of the equal opposite reaction thing, the cart pushes back on the horse, so the horse starts accelerating backwards, away from the cart. They both accelerate in opposite directions from where they started. BUT . . . their common center of mass doesn't move, and the sum of their momentums (which are in opposite directions) remains zero.
