1.	The direction of projectile at certain instant is inclined at angle a to the horizontal. After t sec, if it is inclined at an angle betathen 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
