<u>Answer:</u> The force exerted on the object is 7000 N
<u>Explanation:</u>
Force is defined as the push or pull on an object with some mass that causes change in its velocity.
It is also defined as the mass multiplied by the acceleration of the object.
Mathematically,

where,
F = force exerted on the object
m = mass of the object = 2000 kg
a = acceleration of the object = 
Putting values in above equation, we get:

Hence, the force exerted on the object is 7000 N
