Two charged balls moving in the same direction with same velocity v are placed in an electric field. After some time, one ball moves with velocity v/2 at an angle of 60^(@) with the initial direction and the other ball moves at right angles to the initial direction with a velocity v'. Then, the value of v' is

Answer»

`v/sqrt2`
`v/sqrt3`
`v/2`
v
