The linear expansivity of A and B are alpha_(1) and alpha_(2) respectively. If the cubical expansivity of B is 3 times the superficial expansivity of A, then

The linear expansivity of A and B are alpha_(1) and alpha_(2) respecti

1.	The linear expansivity of A and B are alpha_(1) and alpha_(2) respectively. If the cubical expansivity of B is 3 times the superficial expansivity of A, then
Answer» `alpha_(2) = 2 alpha_(1)` `alpha_(1) = 2 alpha_(2)` `alpha_(2) = 3 alpha_(1)` `alpha_(1) = 3 alpha_(2)` ANSWER :A
