Hello!
If you are referring to the mercury substance, mercury is a bright red color, usually used in early thermometers and is deadly if humans have a lot of constant with this substance
The force acting on the object will be 32 N.
Newton's second law of motion states that, "the force is equal to the change in momentum per change in the time". The mathematical form of the law is given below.

Where P = momentum, t = time, m =mass, v = velocity, a = acceleration and F = force.
The mass of the object is 4 kg and acceleration is 8 m/s^2. Substitute the values in the equation and we will get the force.
F = ma
F = 4 kg * 8 m/s^2
F = 32 kg.m/s^2
F = 32 N
