1.	An electron of mass m and charge q is accelerated from rest in a uniform electric field of strength E. The velocity acquired by it as it travels a distance l isA. `[(2Eql)/m]^(1//2)`B. `[(2Eq)/(ml)]^(1//2)`C. `[(2Em)/(ql)]^(1//2)`D. `[(Eq)/(ml)]^(1//2)`
Answer» Correct Answer - A `v=sqrt((2qV)/m)(V=E.l)` `therefore" "v=sqrt((2qEl)/m)` `v=((2qEl)/m)^(1//2)`
