Acar is travelling at a constant speed on a flat road
true or false
-the car is in equilibrium (t/f)
-the car is accelerating (t/f)
-there is a net force on the car (t/f)
-there is work being done on the car (t/f)

The car is in equilibrium, false. Because the net movement of a body in equilibrium is zero. Since the car is moving it is not in equilibrium

The car is accelerating, false. Because the car is travelling at constant speed, the change of speed of the car per unit time is zero.

There is a net force on the car, true

There is work being done on the car, true

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

explanation:

v=uf/(u-f)
