Answer 1

Answer:

Showing results for A vector of magnitude 10 units makes an angle of 30 degree with x axis .find its component along x axis and y axis ...

Search instead for A vevtor of magnitude 10 unit makes an angle of 30 degree with x axis .find its component along x axis and y axis ...

Answer 2

Answer:

In component form

A=[10 cos 30^o, 10 sin 30^o]= (8.66,5)

B=[-20cos 30^o,20sin30^o]=(-17.32, 10)

Therefore A+B=[ 8.66–17.32,5+10]=(-8.66,15)

Magnitude of A+B is sqrt[-8.66^2+15^2]=17.32 units.
