Vector vec(a) is increased byDelta vec(a) . If increment in magnitude of vec(a) is greater than magnitude of increment vector then angle between vec(a)andDelta vec(a) is :

Vector vec(a) is increased byDelta vec(a) . If increment in magnitude

1.	Vector vec(a) is increased byDelta vec(a) . If increment in magnitude of vec(a) is greater than magnitude of increment vector then angle between vec(a)andDelta vec(a) is :
Answer» greater than ` PI //6` EXACTLY ` pi //6` exactly ` pi //2` `phi` ANSWER :D
