\n" ); document.write( " Struggling on this particular question, on vectors and scalars, was just wondering if anybody could help.\r
\n" ); document.write( "\n" ); document.write( "a) Draw an xy plane and show the vectors a=2i+3j and b=5i+j (need not be to scale). By constructing the appropriate parrallelogram, draw the resultant vector in terms of i and j.\r
\n" ); document.write( "\n" ); document.write( "b) A particle P is acted upon by forces (measured in Newtons) F1= 3i-2j+5k F2= -i+7j-3k, F3= 5i-j+4k and F4 = -2j+3k. Show the magnitude of the resultant force F acting on P is sqrt134 Newtons.\r
