JEE MainPhysicsElectrostaticsMCQ+4 / −1

Two charges, each equals to

q,

are kept at

x=-a

and

x=a

on the

x

-axis. A particle of mass

and charge

{q_0} = {q \over 2}

is placed at the origin. If charge

{q_0}

is given a small displacement

\left( {y \lt \lt a} \right)

along the

y

-axis, the net force acting on the particle is proportional to

A
$y$
B
$-y$
C
${1 \over y}$
D
$-{1 \over y}$
