Problem

Two point charges

Q

each are placed at a distance

d

apart. A third point charge

q

is placed at a distance

x

from mid-point on the perpendicular bisector. The value of

x

at which charge

q

will experience the maximum Coulomb's force is : (A)

x = d

(B)

x = \frac{d}{2}

(C)

x = \frac{d}{\sqrt{2}}

(D)

x = \frac{d}{2\sqrt{2}}
