in the solution it is given that they make an angle 45 degree with x axis . but what is the reason ?
why cant there be any other angle ? need an explanation.
nice ! thanks
@Viraam_Rao is it necessary that theta has to be 45 degree ? or it can be any other value ?
Not necessary bro. From that figure, for any ϴ they will be perpendicular to each other after collision given that masses are equal.
ok , thanks @Viraam_Rao bro
