A vector of magnitude 10 units  makes an angle $60°$with X- axis  in XY plane . Then

A) component along Y axis is $10\sin 60=5\sqrt{3}$

B) component along Z axis is $10\cos 90=0$

C) vector is given by$10\cos 60i+10\sin 60j=5i+5\sqrt{3}j$

D) vector is given by $10\cos 60-10\sin 60j=5i-5\sqrt{3}j$
