An electron beam accelerated from rest through a potential difference of 5000 V in vacuum is allowed to impinge on a surface normally. The incident current is 50`muA` and if the electrons come to rest on striking the surface the force on it is

An electron beam accelerated from rest through a potential difference of 5000 V in vacuum is allowed to impinge on a surface normaly. The incident current is muA and if the electrons come to rest on striking the surface the force on it is:

An electron beam after being accelerated from rest through a potential difference of 500 V in vacuum is allowed to impinge normally on a fixed surface. If the incident current is 100muA , determine the force exerted on the surface assuming that it brings the electrons to rest. (e=1.6xx10^(-19)C,m=9.0xx10^(-31)"kg")
