In a certain region of space a uniform and constant electric field and a magnetic field parallel to each other are present. A proton is fired from a point A in the field with speed V=4xx10^(4)m//s at an angle of alpha with the field direction. The proton reaches a point B in the field where its velocity makes an angle beta with the field direction. If (sinalpha)/(sinbeta)=sqrt3. Find the electric potential difference between the points A and B. Take mp (mass of proton) =1.6xx10^(-27) kg and e (magnitude of electronic charge) =1.6xx10^(-19) C.
