ge You are logged in as Gavin Ritches Two identical charged particles are 5.0 m apart. If the charge on one of the particles is 1.9e-6 Coulombs, what is the value of the force between them? Answer: Next page 11 28

A +30 nC charge is placed at a distance r = 5 mm from a +10 nC charge in free space. Calculate the magnitude of the force between the charges. Note: ε0=8.85x10-12 Fm-1

Four charged particles, each of magnitude Q, are located on the corners of a square of edge a.a) What is the magnitude of the force acting onone of these charges?b) What is the work required to bring a fth charge Q from the innity to the center of the square

I Two point charges, -10 nC and +15 nC, are held fixed a distance 0.50 m apart. (a) Where can a +20-nC charge be placed so that the net force on it is zero? (b) Repeat part (a) if the third charge is -20 nC.

a point particle with a positive charge q and a mass is held stationary by the forces of gravity ad electricity above an infinitely,thin,plane sheet of positive charge with charge positive density? what is the value of density
