Two large metal plates of area 0.7 m2 face each other. They are 5.1 cm apart and have equal but opposite charges on their inner surfaces. If the magnitude E of the electric field between the plates is 55 N/C, what is the magnitude of the charge on each plate? Neglect edge effects.

Explanation:

The given data is as follows.

    Area (A) = 0.7 .

  Electric field between the plates, (E) = 55 N/C

Since, electric field is related to surface charge density as follows.

Also,    E =

or,        

Therefore, charge will be calculated as follows.

          Q =

             =

             =

             = 341 pC

Thus, we can conclude that magnitude of the charge on each plate is 341 pC.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
