Yes.
The acceleration vector WILL point south when the car is slowing down while traveling north
Answer:
Objects move according to their net force, or the total amount of force acting on them. Balanced forces are just that, balanced. An object with balanced forces will not move because the opposing forces will cancel each other out. However, if there are unbalanced forces, the object will move in accordance with the force that is greater. When moving though, there is always friction. Whether you be underwater, on the ground, or in the air there is always friction on the Earth. (Besides vacuums, of course.)
Force is equal to mass x acceleration.
With that you can find the forces of the object if you know its mass and acceleration.
Explanation:
The motion of an object can be described in many ways, including path, speed, velocity, and acceleration.
Answer:
Charge on A is
Charge on B is
, then ![q_2=2q](https://tex.z-dn.net/?f=q_2%3D2q)
Distance between two charges = 16 cm = 0.16 m
Force F = 43 N
According to coulombs law force between tow charges is given by
, here K is constant which value is
So ![43=\frac{9\times 10^92q^2}{0.16^2}](https://tex.z-dn.net/?f=43%3D%5Cfrac%7B9%5Ctimes%2010%5E92q%5E2%7D%7B0.16%5E2%7D)
![q^2=0.0611\times 10^{-9}](https://tex.z-dn.net/?f=q%5E2%3D0.0611%5Ctimes%2010%5E%7B-9%7D)
![q^2=0.611\times 10^{-10}](https://tex.z-dn.net/?f=q%5E2%3D0.611%5Ctimes%2010%5E%7B-10%7D)
so charge on A is
And charge on B is ![2q=2\times 0.7820\times 10^{-5}C=1.5640\times 10^{-5}C](https://tex.z-dn.net/?f=2q%3D2%5Ctimes%200.7820%5Ctimes%2010%5E%7B-5%7DC%3D1.5640%5Ctimes%2010%5E%7B-5%7DC)
