Find the resultant of the vectors vec(OA), vec(OB), vec (OC) as shown in figure. The raidus of the circle is r. |
|
Answer» SOLUTION :`VECR=vec(OA)+vec(AB)+vec(OC)` `vecR= rhati+r COS 45 I +r sin45 hatj+r hatj` `vecR=(r+(r)/(sqrt(2)))hatj+(r+(r)/(sqrt(2)))hatj` `|vecR|= (sqrt(2r)+tau)` along `vec(OB)`
