Pa-10000 *.050-.98 * 10000 * .050 = Pb-10000 * .100.
Pa-Pb = 500+490-1000.
Pa-Pb = -10N/m^2.
Pa-Pb = 500+490-1000.
Pa-Pb = -10N/m^2.

Pressure due to water=10000*1*0.05 = 500,
Pressure due to oil=10000*0.98*0.05 = 490,
Diff=490-500 = -10.
It is already a specific weight no need to multiply by 9.81.
Pressure due to oil=10000*0.98*0.05 = 490,
Diff=490-500 = -10.
It is already a specific weight no need to multiply by 9.81.

Pa-1 * 10000 * 50 * 10^(-3)-0.98 * 10000 * 50 * 10^(-3) = Pb-1 * 10000 * 100 * 10^(-3).
Pa - Pb = -10.
Pa - Pb = -10.

Pressure = density * gravity * height.

Pressure due to water=10000*1*9.81*0.05 = 490.5.
Pressure due to oil=10000*0.98*9.81*0.05 = 480.5.
Diff=480.5-490.5 = -10.
Pressure due to oil=10000*0.98*9.81*0.05 = 480.5.
Diff=480.5-490.5 = -10.
