an electron is emitted with negligble speedfrom negative plate of a parallel plate capacitor charged to a potential differenc V. the seperation between the plate s is d and a magnetic field B exists in the space as shown in figure. show that the electron will fail to strike the upper plate if d>[2meV/eB2]1/2
