Two balls of charges qr and q2 initially have a velocity of the same magnitude and direction. After a uniform electric field has been applied for a certain time interval, the direction of first ball changes by 60° and the ve- locity magnitude is reduced by half. The direction of velocity of the second ball changes thereby 90°. In what ratio will the velocity of the second ball change? Determine the magnitude of the charge-to-mass ratio of the second ball if it is equal to a for the first ball. Ignore the electrostatic interaction between the balls.
