Two electrons in the atom are seperated by 1.5x10^-10 m, the typical size of an atom. What is the electric force between them?
A positive and negative charge, each of magnitude 2.5x10^-5 C,are seperated by a distance of 15cm. Find the force of each particles.
A force of 2.4x10^2 N exsits between a pos. charge of8.0x10^-5 C and a pos charge of 3.0x10^-5C. What distance seperates them?
Two identical pos charges exert a replusive force of 6.4x10^-9N when seperated by a distance of 3.8x10^-10m. Calculate the charge of each.
