If they are not coplanar, you would need at least four forces to get a net force (resultant force) of zero.
EF=0 means when the net force on something is 0 (zero).
Zero is.
As we know equipotential surface means there is no potential difference that is no work is done on surface.so lines of force must intersect surface at right angles to satisfy this statement,so that net work is zero.
The term "steady speed" indicates a constant velocity. This implies that there is no net acceleration, and thus no net force. Any net force on a moving object will cause a change in velocity, as per Newton's First and Second Laws.
If the net force is not zero then the object will move in the direction of the greater force.
When the net force=0, absolutely nothing happens. no movement at all.
Inertia will not be affected when "net" or "net force" is zero.
Net force is defined as the overall force acting on an object. When a cat sleeps on a table, the net force on it is zero. When a body is at rest the net force acting on the body is zero.
If the net force acting on a motionless object is not zero, the object will start to accelerate in the direction of the net force. Newton's second law states that an object will accelerate in the direction of the net force applied to it, causing a change in its velocity.
When an objects net force is zero, its acceleration is zero. No force , no acceleration.
If an object is at rest, the net force acting on it is balanced - meaning the forces pushing in one direction are equal to the forces pushing in the opposite direction. This results in a net force of zero, keeping the object stationary.
Balanced force -> Zero net force -> Zero acceleration (stays at rest or constant velocity)
Zero net force is when the forces are balanced and there is no acceleration.
When forces are balanced, the net force is zero.
