two identical balls of charges Q1 and Q2 initally have equal velocity of d same magnitude and direction.after a uniform electric field is applied for sometym ,the direction of d velocity of d first ball changes by 60. and d magnitude is reduced by half.the direction of d velocity of d second ball changes there by 90. .in what proportion will the velocity of second ball changes????the curect ans is v/<3>......where<$>...means under-root $...!!give me a curect solution wid a curect explaination!!THanKu...n plz do open my profile.....see the posted ques....n reply 'em.....i dint get reply f d ques i'hv sent!!!
