The main resistive force that opposes the driving force when a vehicle is moving is Drag Force/ Air resistance. Air resistance is the frictional force exert by air on the moving body. Greater the velocity of the body, more it will experience air resistance. Air resistance tries to slow down the slow down the speed of the body. The force by engines tries to move it forward and drag force tries to move it in opposite direction. If the force by car engine is greater than the drag force, car will move forward.
To find the net charge you take the number of protons and subtract the number of electrons, and the answer will be your charge.
This atom has 11 electrons AND 11 protons
11 - 11 = 0 net charge
