Two identical balls of charge `q_(1)` & `q_(2)` initially have equal of the same magnitude and direction. After a ubiform electric field is applied for some time, the direction of the velocity of the first ball charges by `60^(@)` and the magnitude is reduced by half. The direction of the velocity of the second ball charges there by `90^(@)`. In what proportion will the velocity of the second ball changes?

Two balls of charges q_(1) and q_(2) initially have a velocity of the same nagnitude and direction. After a unform electric field has been applied for a certain time. The direction of the first ball changes by 60^(@) and the velocity magnitude is reduced by half. The direction ofvelocity of the second ball changes by 90^(@) . In whata ratio will hte velociyt of the second ball change? Determine, the magnitude of the charge to mass ratio of the ball if it is equal to alpha_(1) for the firt ball. Ignore the electrostatic interactin between the balls. ,
