Use that:
Then use the 2nd Newton's Law of Motion:
At x = 0.3 and y = 0.6, we can find the acceleration as:
(in SI unit)
Then the magnitude of the acceleration on that point is:
(SI Unit)

Answer:
1) 916 kg/m³
2) 9.8566×10⁴ Pa
Explanation:
1) Originally, the water is at the same level on both sides. When the oil is added, one side goes down 67.5 mm and the other side goes up 67.5 mm. The top of the oil is 12.3 mm above the water, so the total height of the oil relative to the low end of the water is:
12.3 mm + 67.5 mm + 67.5 mm = 147.3 mm
And the height of the water relative to the low end is:
67.5 mm + 67.5 mm = 135 mm
The pressure at the bottom of the oil equals the pressure of the water at the same elevation.
P = P
ρgh = ρgh
ρh = ρh
ρ (147.3 mm) = (1000 kg/m³) (135 mm)
ρ = 916 kg/m³
2) P = ρgh
P = (1.3608×10⁴ kg/m³) (9.7835 m/s²) (0.74035 m)
P = 9.8566×10⁴ Pa
