An electron beam after being accelerated...

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")`
