Problem

Three point charges are fixed in the

xy

-plane as follows:

+1.5\,\mu\text{C}

at

( -0.60\,\text{m},0)

,

+1.5\,\mu\text{C}

at

(+0.60\,\text{m},0)

, and

-1.5\,\mu\text{C}

at the origin. Along the

y

-axis (

x=0

), at what positive value of

y

is the electric potential equal to zero? a)

0.60\,\text{m}

b)

0.35\,\text{m}

c)

0.78\,\text{m}

d)

0.30\,\text{m}
