A point charge q14nc is placed at the origin and a second, Ask an Expert

Academics

Q. A point charge q1=4nC is placed at the origin, and a second point charge q2= -3nC is placed on the x-axis at x= 20cm. A third point charge q3=2 nC is to be placed on the x-axis between q1 and q2.

i.) What is the potential energy of the third charge if it is placed at x= 10.00cm.

ii) Where should the third charge be put to make it's potential energy 0?
