Points A,B and C are at the corners of an equilateral triangle of side 3 metres. equal positive charges of 2 micro-Coulombs are at A and B respectively. What is the potential at C??
The potential at a distance "r" from a point charge of Q is given by:percy_07 said:Points A,B and C are at the corners of an equilateral triangle of side 3 metres. equal positive charges of 2 micro-Coulombs are at A and B respectively. What is the potential at C??
Point charges are hypothetical particles with a positive or negative charge that are infinitely small in size and have no physical dimensions.
Point charges interact with each other through the electromagnetic force, which can either attract or repel them depending on the charges' polarity.
The equation for the force between two point charges is F = (k*q1*q2)/r^2, where k is the Coulomb's constant, q1 and q2 are the charges, and r is the distance between the charges.
The direction of the force between two point charges is determined by the charges' polarity. Like charges repel each other, while opposite charges attract each other.
Point charges can be used in various practical applications, such as in electronic devices, particle accelerators, and in studying the behavior of atoms and molecules.
