Question

Could someone please show me how to do this problem? Two point charges are on the y-axis. A 4.0 µC charge is located at y =1.45 cm, and a -2.34 µC charge is located at y =-1.10 cm. (a) Find the total electric potential at theorigin.
1 V

(b) Find the total electric potential at the point havingcoordinates (1.50 cm, 0).

Explanation / Answer

a) Total electric potential original is                    V =[(8.9*109N.m2/C2)(4.0*10-6C)/(1.45*10-2m)] +[(8.9*109N.m2/C2)(-2.34*10-6C)/(1.10*10-2m)] b) The total electric potential at the point havingcoordinates (1.50 cm, 0) is             V=  [(8.9*109N.m2/C2)(4.0*10-6C)/(2.086*10-2m)] +[(8.9*109N.m2/C2)(-2.34*10-6C)/(1.86*10-2m)] Simplifying we get the answer.
