An electron is liberated from the lower of the two large parallel metal plates separated by a distance of 20 mm. the upper plate has a potential of `+2400 V` relative to the lower plate. How long does the electron take to reach the upper plate ? Take `(e )/(m)` of electrons `1.8xx10^(11) C kg^(-1)`

An electron having charge e and mass m starts from the lower plate of two metallic plates separated by a distance d . If the potential difference between the plates is V , the time taken by the electron to reach the upper plate is given by .

An electron having charge e and mass m starts from the lower plate of two metallic plates separated by a distance d . If the potential difference between the plates is V , the time taken by the electron to reach the upper plate is given by .

Two parallel plates kept in air 5 cm apart are at a potential difference of 500 V . If there be an electron (ii) kinetic energy an (iii) velocity of the electron, when it reaches the other plate.

The p.d between two plates separated by a distance of 1 mm is 100V .The force on an electron placed in between the plates is

An electron enters between two horizontal plates separated by 2 mm and having a potential difference of 1000V . The force on electron is

A partical having charge that of an electron and mass 1.6xx10^(-30) kg is projected with an initial speed u at the angle 45^(@) to the horizontal from the lower plate of a parallel-plate capacitor as shown in fig. The plates are suffiecienly long and have a separation of 2 cm, find the maximum value of the velocity of he particle so that it does not hit the upper plate. Take the electric field between the plates as 10^(3)Vm^(-1) directed upward.
