Question

A particle of mass m and charge q is placed rest in a uniform electric field E and then released- The kinetic energy attained by the particle after moving a distance y is -qE-y-2-q-E-2-yqEy-q-2-Ey

K-E acquired - work done- force-xD7- distance -qE-xD7-y-qEy

A particle of mass $m$ and charge $q$ is placed at rest in a uniform electric field $E$ and then released. The kinetic energy attained by the particle after moving a distance $y$ is :
$q E y^{2}$
$q E^{2} y$
$q E y$
$q^{2} E y$

K.E acquired $=$ work done
$=$ force $\times$ distance $= q E \times y = q E y$

A particle of mass m and charge q is placed at rest in a uniform electric field E and then released. The kinetic energy attained by the particle after moving a distance y is :qEy2qE2yqEyq2Ey

K.E acquired = work done= force× distance =qE×y=qEy

A particle of mass $m$ and charge $q$ is placed at rest in a uniform electric field $E$ and then released. The kinetic energy attained by the particle after moving a distance $y$ is :
$q E y^{2}$
$q E^{2} y$
$q E y$
$q^{2} E y$

K.E acquired $=$ work done
$=$ force $\times$ distance $= q E \times y = q E y$
