Four Point Charges of Magnitude 6

question 25

Short Answer

Four point charges of magnitude 6.00 μC and of varying signs are placed at the corners of a square 2.00 m on each side, as shown in the figure. (k = 1/4πε0 = 8.99 × 10⁹ N ∙ m²/C²)
(a) What is the electric potential (relative to infinity) at the center of this square due to these charges?
(b) What is the magnitude of the electric field due to these charges at the center of the square?

Definitions:

Synaptic Vesicles

Small sacs within presynaptic nerve terminals that store neurotransmitters, which are released into the synaptic cleft during neurotransmission.

Action Potential

A brief change in electrical voltage that occurs between the inside and the outside of an axon when a neuron is stimulated; it serves to produce an electrical impulse.

Synaptic Cleft

The gap between two neurons where neurotransmitters are released to transmit signals.

Neurotransmitters

Chemical messengers in the nervous system that transmit signals across synapses from one neuron to another.
