A positive point charge q 236 nc is located at x 120 m, Ask an Expert

Academics

A positive point charge q = +2.36 nC is located at x = 1.20 m and a negative charge of -2q = -4.72 nC is located at the origin as in the following figure.

(a) Sketch the electric potential versus x for points along the x-axis in the range -1.50 m < x < 1.50 m.

(b) Find a symbolic expression for the potential on the x-axis at an arbitrary point P between the two charges. (Use the following as necessary: x.)

(d) Find the point along the x-axis between the two charges where the electric potential is zero.
