A stream of electrons moving with 3xx10^(7)ms^(-1) gets deflected by electric field of 18 V/ cm normal to their path. What is its transverse deflection in travelling through a horizontal distance of 10 cm in the field ?(m_(e)=9xx10^(-31)kg): |

Answer» 0.177 cm `a=(X*e)/(m)=(1800xx1*6xx10^(-19))/(9xx10^(-31))=32xx10^(13)` `x=(10)/(100)=3XX10^(7)x t or t=(1)/(3xx10^(8))` SEC. `y=(1)/(2) at^(2)=(1*6)/(9)=0*177 cm` |
