The tension in the cable is equal to the mass of the car is 8150N.
If the car is pulled over a ramp with a light cable and there is no friction there.
Then it means that the total tension in the cable will be equal to the total mass of the car.
The mass of the car is given to be 815 kg.
As the car is under the influence of gravity, the acceleration due to gravity will be working on the car,
So, we can write,
Tension in the cable = Weight of the cable
T = Mg
T is the tension,
M is the mass of car,
g is acceleration due to gravity whose value is 10m/s²
So, putting all the values,
T = 815(10)
T = 8150 N.
So, the total tension in the cable is 8150N.
