A) zero
B) \[QE\]
C) \[\frac{1}{2}QE\]
D) \[2QE\]
Correct Answer: C
Solution :
: Intensity of field\[E=\frac{q}{{{\varepsilon }_{0}}A}=\frac{Q}{{{\varepsilon }_{0}}A}\] Force between plates \[=\frac{{{q}^{2}}}{2{{\varepsilon }_{0}}A}=\frac{{{Q}^{2}}}{2{{\varepsilon }_{0}}A}\] \[=\frac{q}{2}\times \frac{q}{{{\varepsilon }_{0}}A}=\frac{qE}{2}=\frac{QE}{2}\]You need to login to perform this action.
