We consider three point charges. 91 All three charges are held in place. q1=+3.651e-5 Cat (4,6) meters. q2=+3.61e-5 Cat (4,0) meters. q3 = +3.651e-5 Cat (0,3) meters. 93 %3D Calculate the electric potential energy of this charge configuration in joules. * starting symbolic equation(s) must be written before being used 92 Three charges located in an x,y plane.

1) One theory about charging insulators is called adhesion. Look this up and explain (in about 3-4 sentences) why charge transfers between two insulators that are rubbed together. 2) Describe what happens to the charge on a neutral metal sphere if a charged rod is brought near (but not touching) the sphere. 3) Does the sphere in the previous question remain neutral?

electrical Potential in volts Pont (x,y) is V= (4y) f(x, y) = eTan %3D Determin for the the direction of movemen t int for for max rate of decrease In electrical potential and what is that rate of decrease?
