Question

Avector of magnitude of 10 N acting in XY-plane
has components 8 N and 6 N along positive X-
axis and positive Y-axis, respectively. The coor-
dinate system is rotated about Z-axis through
angle 90° in anti-clockwise direction.
Find x-component and y-component in new
coordinate system.

Answer:

Avector of magnitude of 10 N acting in XY-plane

has components 8 N and 6 N along positive X-

axis and positive Y-axis, respectively. The coor-

dinate system is rotated about Z-axis through

angle 90° in anti-clockwise direction.

Find x-component and y-component in new

coordinate system.
