Question

i need the explantion of the answer please

2) For three given electric charges (see the figure below), calculate the total electrie potential d(r) in points "A" and "B" using the superposition principle. Give the anser in terms of Q and R. for k,1 Vm/C unit system Problem 2 Let's choose the origin at the location of the first charge. Then z-0: 2R -3R: zA-2R: za-4R swer 4Q z)- + -3R 5Q 3R -R 2Q A)= and o(B) 40 9-+0 A It (MORE PROBLEMS on the other page!!!) 6.'32 2.69

Answer 1

The fotential at Point ? due to charge v chare a and pointP distance between V k where x fox he V V Potential at Point Potential at Potnt A due to 4, -2Q 4 Q due to V V 4Q 4- R+R Potential at point & due to V, Potential at Potnt A dueto v 3R R Potential at point& dueto 1 Potential at Point Adue Q. -Q R Resultant fotential at fbint B Resultant fotential at point A +_ +V -2a Q V= 3R V Q 2Q 3R Ve -2Q V= 3R
