Question

the components of a vector r along X axis. will have maximum value if
1) r is along positive y axis

2) r is positive X axis

3)r make an angel of 45° with the X axis

4)r is along negative y axis​

Answer 1

Answer:

3.r makes an angle of 45 with x axis

Answer 2

Explanation:

The component should be at an angle of 0 degree

from the axis given here and thus the component of the vector along x-axis will have the maximum value when r is along x-axis.
