with a -1 iron charge it becomes an electrode
Explanation:
There is a force of 3N acting towards the left and 2 forces of 4N each acting towards the right.
Net force = (4N) + (4N) - (3N) = 5N towards the right.
P.S. We subtract the 3N force because the forces are in opposite directions.
The neuron is the functional unit of the nervous system.
Answer:
C) They will accelerate away from each other
Explanation:
Just like magnets, if the charges are the same, the point charges will repel one another. They will exert a net force in opposite directions, and will thus accelerate away from one another.
