3. Draw diagrams to show two vectors 'a' and F and the vectors 'a' + T; and tr' F. (6 marks) a. When is the magnitude of E' + 3\" more than that of E\" $3 in. When is the magnitude of 3' + 3'. less than that of E\" $3 c. When is the magnitude of E' + 3\" equal to that of E\" F'? d. When is 'e' + E\" = W + it\"? e. When is the minimum value of 'E + 3\"? \fwhen p > go (a+ 3) then . (8 - 31 la+ b /
