1. A large flat metal surface has uniform charge density + σ. An electron of mass m and charge e leaves the surface at point A with speed ν, and return to it at point B. The maximum value of AB is 1) νm∈0σe 2) ν2m∈0eσ 3) ν2e∈0σm 4) ν2σe∈0m

Electric field due to large metal plate 
E = σ / 2ε
Projected electron motion will be like curved path , having projectie.
AB will be maximum when Q= 45 degree
a = row* E / m 
=> P*σ/ 2ε* m
 
Further calculate and check for ans,
