Or we can say that
----1
Where d is the distance between two plates ,A is the area.
When K=4.2 and distance become double

----2
Now from equation 1 and 2

So

ITS TURE.When there is no torque acting on a body, its angular momentum is constant. Net force changes momentum, while net torque changes angular momentum.
Acceleration is a change in speed, so if the car has a constant speed then it's acceleration is 0m/s^2.
