The direction of projectile at certain instant is inclined at angle al

1.	The direction of projectile at certain instant is inclined at angle alpha to the horizontal. After t sec, if it is inclined at an angle beta then the horizontal component of velocity is
Answer» `(G)/(TAN alpha - tan beta)` `(GT)/(tan alpha - tan beta)` `(t)/(g(tan alpha - tan beta)` `(gt)/(tan alpha + tan beta)` Answer :B
