1.	The coefficients of linear expansion of P and Q are alpha_(1) and alpha_(2)respectively. If the coefficient of cubical expansion of 'Q' is three times the coefficient of superficial expansion of P, then which of the following is true ?
Answer» `alpha_(2) = 2 alpha_(1)` `alpha_(1) = 2alpha_(2)` `alpha_(2) = 3 alpha_(1)` `alpha_(1) = 3alpha_(2)` ANSWER :A
