Four point charges, each of magnitude 7.76e-6 C are placed at the corners of a square 39.6 cm on a side. If three of the charges are positive and one is negative, find th emagnitude ofthe force experienced by the negative charge. Answer in units of N.

Question

anonymous · Answer

Just compute the coloumbic force between each of the positive of particles and the negative one, being careful to note direction, and sum them.

coulombs law, yo!  F=k(qxq)/r^2

anonymous · Answer

use superposition to find the total force from all charges.

anonymous · Answer

i dont know how to find direction of the charges when adding them.
