Question

the component of a vector a along y axis will have maximum value if​

Answer 1

Answer:

The component of a vector a along y axis will have maximum value if A is along positive Y-axis

Explanation:

Answer 2

answer : option (b) a is along positive y-axis.

explanation : we know, if two vectors a and b are given, then component of a along the direction of b = |a|cosα, where α is angle made between a and b.

similarly, component of balong the direction of a = |b|cosα.

Let vector a makes an angle β with y-axis. then, component of vector a along the direction of y-axis = |a|cosβ

now plz tell me, when |r|cosβ will be maximum.

yes of course , when β = 0°

it means,component of a vector r along y-axis will have maximum value if r is along positive y - axis.
