Problem 2: (15 pts) a 10-m high cylindrical container is half-filled at the bottom with water of density =1000 kg/m3 while the top half is filled with oil of specific gravity of 0.85. what is the pressure difference between the top and bottom of the container?

Explanation:

specific gravity of oil is

we know that

change in pressure  for oil is given as

here density and h is for oil

change in pressure  for WATER is given as

here density is for water and h is for water

pressure change due to both is given as

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
