If an electron is accelerated by 8.8xx10^(14)ms^(-2), then electric field required for this acceleration is (given specific charge of the electron =1.76xx10^(11)Ckg^(-1)):

Answer»

`40Vcm^(-1)`
`50Vcm^(-1)`
`60Vcm^(-1)`
`70Vcm^(-1)`

SOLUTION :Electric field `E=(F)/(e)=(ma)/(e)=(a)/((e)/(m))=5XX10^(3)V//m =50 V CM^(-1)`
