Q. The charge $q$ is projected into a uniform electric field $E,$ work done when it moves a distance $Y$ is
A) $qEY$
B) $\frac{qY}{E}$
C) $\frac{qE}{Y}$
D) $\frac{Y}{qE}$
Explanation
(a) Work done in moving a charge $q$ into a uniform electric field $E\ $ through a distance $Y$ is
work done$= Force \times distance$
$\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ = (qE) \times r = qEY$
