Both the capacitorsshownin figure are made of square plates of edge a . The separations between the platesof the capacitorsand d_(1) and d_(2) as shown in the figure. A battery of V volt and a resistance R are connectedas shown in figure. At steady state an electron is projected between the plates of the lower capacitor from its lower plate along the plate as shown. Minimum speed should the electron be projected is given by (1)/(sqrt(n))((Vea^(2))/(md^(2)))^(1//2) so that it does not collide with any plate? Consider only the electric forces then find the value of n. |
