A Uniform Electric Field $\overrightarrow { \mathbf { E } } _ { \mathrm { I } }$

question 86

Multiple Choice

A uniform electric field $\overrightarrow { \mathbf { E } } _ { \mathrm { I } }$ is present in the region between the infinite parallel planes of charge A and B,and a uniform electric field $\overrightarrow { \mathbf { E } } _ { \text {II} }$ is present in the region between the infinite parallel planes of charge B and C.When the planes are vertical and the fields are both non-zero,

• A) \(\overrightarrow { \mathbf { E } } _ { \mathrm { I } }\) and \(\overrightarrow { \mathbf { E } } _ { \text {II } }\) are both directed to the right.
• B) \(\overrightarrow { \mathbf { E } } _ { \mathrm { I } }\) and \(\overrightarrow { \mathbf { E } } _ { \text {II } }\) are both directed to the left.
• C) \[\overrightarrow { \mathbf { E } } _ { \mathrm { I } }\] points to the right and \[\overrightarrow { \mathbf { E } } _ { \text {II} }\] to the left.
• D) \(\overrightarrow { \mathbf { E } } _ { \mathrm { I } }\) points to the left and \(\overrightarrow { \mathbf { E } } _ { \text {II } }\) to the right.
• E)Any one of the above is possible.
