Four point charges, each of magnitude 12.6 µc, are placed at the corners of a square 92.7 cm on a side. if three of the charges are positive and one is negative, find the magnitude of the force experienced by the negative charge. the value of coulomb’s constant is 8.98755 × 109 n · m2 /c 2 . answer in units of n

Explanation:

F is the electric force K is the coulomb,s constant equal to 8.98755x10 9N .m2/C 2 Q'anf Q2 are two charges d is the distance between two charges First, let's compute the force between the two positive charges denotes as F1. F1=(8.98755×10 N.m2/C2)(+53×10×10-6 C)/35cm *1m/100cm)2 F 1=206.09 N
