Question

Two small, identical spherical conductorscarry charges of 5.1 C and 2.3 C. They are separated by adistance of 52.0 cm. Calculate the magnitude of the electrostaticforce between these two spheres. How are you supposed to calculate themagnitude if there is no given angle? I dont know if these twocharges lie on a line or within the points of a triangle? Pleasehelp!

Explanation / Answer

For two small given spheres, with no given radii, we considerthese to be point charges. ----- There is no angle needed to observe the electrostatic forcebetween point charges, all that matters hereis the distance between the charges (because they areassumed to be infinitesimal points). You simply need touse: Coulomb's Force Law: F = kQq/r2 ----- Assuming both spheres carry a positive charge, there will be aforce of repulsion between the charges. ------ F = k(5.1C)(2.3C)(10-12)/(0.520m)2 ----- Plug in Coulomb's Force constant k, calculate the values andyou're done.  Just remember to check your answer to makesure it makes sense. A force should have units of Newtons, orkg*m/s2. So if you don't end up with N, you'vemade a mistake. ----- I hope this solution was a Lightsaber for you.
