A) \[({{\phi }_{2}}-{{\phi }_{1}}){{\varepsilon }_{o}}\]
B) \[({{\phi }_{1}}+{{\phi }_{2}})/{{\varepsilon }_{o}}\]
C) \[({{\phi }_{2}}-{{\phi }_{1}})/{{\varepsilon }_{o}}\]
D) \[({{\phi }_{1}}+{{\phi }_{2}})/{{\varepsilon }_{o}}\]
Correct Answer: A
Solution :
From Gauss's law, \[\frac{Charge\text{ }enclosed}{{{\varepsilon }_{0}}}=\] Flux leaving the surface \[\frac{q}{{{\varepsilon }_{0}}}={{\phi }_{2}}-{{\phi }_{1}}\] \[\Rightarrow \] \[q=({{\phi }_{2}}-{{\phi }_{1}}){{\varepsilon }_{0}}\]You need to login to perform this action.
