Question

The trail of a vector is on the origin of X Y coordinate axes. The vector is in + X direction. If the vector rotates anti-clockwise, find its X and Y components for the radiation of
(i) 90°(ii) 180° (iii) 270° and (iv) 360°

Answer 1

Answer:

Explanation:

Let say Original Vector

X component  =   A

& Y Component = B

then on rotating anti-clockwise 90°

X Component  = B

& Y Component = - A

then on rotating anti-clockwise 180°

X Component  = -A

& Y Component = - B

then on rotating anti-clockwise 270°

X Component  = -B

& Y Component = A

then on rotating anti-clockwise 360°  ( it is same as origin)

X Component  = A

& Y Component = B
